Direct Connect Overview

What is Direct Connect?

Direct Connect is an option in PETRA which provides a quick link to the IHS Enerdeq Browser

for importing U.S. Well and Production Data via the Internet directly into your PETRA project.

Several import options are available, depending upon whether you are updating an existing

PETRA project or importing well data into a new PETRA project. These options include

selecting an AOI from a map, using an existing PETRA well list, and selecting from your saved

Enerdeq queries, among others. Connection to the Canadian server is also available for access to

Canadian Well and Production Data. This document describes the U.S. connections based on

PETRA version 3.6.1. Notes related to former versions are included at the end of the document.

NOTE: The Direct Connect feature also provides options for linking to IHS Logs,

International data, and Landgrid Shape Files via Map; however, these options are not

discussed in this guide.

Authorization

Use of this feature requires subscription to IHS Well/Production data as well as Enerdeq

authorization, via a Username and Password. If you currently access the Enerdeq Browser, use

that same Username and Password in PETRA.

If you need to establish this authorization, contact your IHS Account Manager. If you are unsure

of the name of your Account Manager, you may contact one of the Customer Care sources listed

below:

Customer Care telephone: 1-800-IHS-CARE (1-800-447-2273); select options for

Enerdeq or PETRA

IHS Enerdeq Customer Care email: [email protected]

PETRA Customer Care email: [email protected]

Initial Setup

You access Direct Connect from the Project menu on the Main module of PETRA.

Project>Direct Connect>IHS US Enerdeq or Canada>Import…

This displays the submenu selections for importing well and production data, as shown below.

Import Wells from IHS Direct Connect

The Well import option allows you to select your wells from a map-drawn AOI, UWI list, or

saved Enerdeq query, among others, depending upon whether you are updating an existing

project or importing to a new project. You can also select the data to load and other import

options, as well as create reports.

TIP: For best results, always import Well data before Production data and set Map Projection

before well import when possible. IHS U.S. data locations are referenced to NAD27

datum.

Import Well Data into a New Project

From the PETRA Main module menu bar, select Project>Direct Connect>IHS US Enerdeq

or Canada>Import Wells from IHS Direct Connect…

An Enerdeq Database Source screen may display. It provides selection of the U.S. or Canada

Well Loader; this depends upon your subscription entitlements.

Select the Database Source, in this case U.S., and click the OK button.

The IHS (US) Well Loader dialog displays once the authorization and connection are verified.

4 June 30, 2011

NOTE: For new projects, the only well selection options available are to select Wells and

AOI from a Map or use a saved Enerdeq Query.

This dialog screen provides the following options:

Wells and AOI: choose method for selecting wells; for new projects, only option A is

available

Import Options: select the data to load and other import options

Queries: select wells from a list of your saved Enerdeq queries; available for new or

existing PETRA projects.

Report: provides a real time visual of the well data import

June 30, 2011 5

Click the OK button to display the map.

Use the Zoom functions to locate your area on the map.

The following example zooms into the area around Wise County, Texas.

Use the Set AOI button to select and set the area of interest.


6 June 30, 2011

Only the wells falling within the AOI (red rectangle) are imported.

Option A1: Accept Current AOI

The AOI rectangle covers an area greater than just Wise County. If this is satisfactory, click the

Get Count button followed by the Use Wells button. This creates the UWI list, closes the map

view, and returns to the IHS (US) Well Loader screen, which shows the current well count

(18,186), the AOI rectangle Lat/Lon extents, and additional selection options.


June 30, 2011 7

Option A2: Filter Current AOI

To reduce the number of wells to just those within Wise County, you can filter the current well

selection by clicking the button, which uses County Codes to filter the data.

If the code is unknown, use the Lookup button. Since county codes may be the same from state

to state, enter the state code for Texas, TX, click the OK button, and then type in the county

name, Wise.

Click the OK button on the County screen. Petra processes the information and returns the three

digit county code of 497.

You can enter multiple counties, and save templates for future use.

Select the OK button. On the IHS (US) Well Loader screen, select the button

to apply the filter. The total well count reduces to 10, 188.

Download Top Selection List to obtain a list from Enerdeq of all formation top names

contained within the list of UWI’s. The list shows the number of occurrences for each formation

top.

NOTE: This request can take several minutes to complete based on the number of UWI’s.

By default, all tops are selected. To restrict the selection list, click the None button, and then

select the tops of interest:


12 June 30, 2011

For consecutive selection, hold the Shift key

For non-consecutive selection, hold the Control key

The Apply Translations button allows you to display the translated top name as established in

the Formation Substitution file on the next tab.

Fm Subst Tab

This screen provides a mechanism to change the names of IHS tops on import, using a name

substitution file.

A formation substitution file can be used to map several formation top names into a common

name. The file has two record types:

The “1” record defines the common name loaded into the database

The “2” record contains the IHS top name to be renamed to the common name

The file format is displayed on the screen.

Click the Browse button and path to the file location.

Use the Test Translations button to verify that the file works correctly.


June 30, 2011 13

This field is used to set the source code for perfs and any zone items created during import.

Formation Tops Source Code to Load

The list provides a method to restrict by source, which IHS tops are imported. Uncheck any

source you do not want to import. Higher numbers (3, 4) provide more reliable top picks.

1 = Driller’s Pick 3 = Operator’s Log Top

2 = Picked from rock sample 4 = IHS modified pick


14 June 30, 2011

Elev Trans Tab

An Elevation Translation file can be used to map several elevation codes to one of the standard

elevation zone items. The file record has two record types:

The “1” record defines the standard name to load to the database

The “2” record contains the IHS elevation code that is to be renamed to the standard

name: KB, DF, GR, and SEIS

The file format is displayed on the screen.

Enable the option and use the Browse button to path to the file; an example is shown above.


June 30, 2011 15

NOTE: Before exiting the Well Data Loader, you can save your settings and AOI by

selecting File>Save Options As… and File>Save AOI File… and load these for future

use.


18 June 30, 2011

View the well import in the Petra Main module. (The number of wells imported is less than the

number to import since the option to Skip IC Numbers was selected.)

Import Well Data to Update Project

These options apply to projects already containing well lists.

Launch the Well Data Loader following the same method as described in the previous section:

Project>Direct Connect>IHS US Enerdeq or Canada>Import Wells from IHS

Direct Connect

NOTE: If this is the first time accessing Direct Connect, the prompt for User ID and

Password displays, as shown in previous section, before the Loader screen opens.

The IHS (US) Well Loader screen displays with additional Well selection options from those in

the previous section.


June 30, 2011 19

Wells and AOI

With an existing well list in your Petra project, several well selection update methods are

available for creating a UWI list of wells to import.

A: Use Map View to Set AOI and Download UWI List

You can use this option to redefine your current AOI. (See previous section).

B: Make AOI and UWI List from Currently Selected Wells

This option uses the wells currently selected in the Main module to create a new AOI and

UWI List.

C: Make UWI List from Currently Selected Wells

Use the currently selected wells in the Main module without modifying the current AOI.

D: Search IHS Server for All Wells within Current AOI Limits

You can use this option to search for all wells in current AOI, and limit the search to

those changed since a specific date. (See example below).

E: Use Previous UWI List

You can use this option to select a previous UWI list.


20 June 30, 2011

Option D: Search IHS Server

This example uses the well list downloaded in the previous section (for a new project) to search

for any wells within the AOI added or modified since the last change date.

There are several options available for restricting the selection of last change date, such as in the

last 2 weeks, or last 30 days; use the dropdown list for selection.

The example below uses the option Since My Last Download. Petra saves the previous

download date and uses that to fill in the Last Change Date.

Enter the Change Date parameters and then click option D.

Click the OK button to enable the search.

The new UWI list displays showing 58 wells added or modified since the last download.


June 30, 2011 21

Import Options

The import options are selected as described in the previous section, with the exception of the

Well Update Mode. In this case be sure to specify Add New Wells and select the appropriate

Update Wells option.

Set the import options or load your saved options file and then click the Import Wells

button.


22 June 30, 2011

The project now reflects 10,180 wells in the project; 1 well added and 57 updated.

June 30, 2011 23

Import Production from IHS Direct Connect

The Production import feature provides several methods for selecting wells, including using

saved queries, as well as various options for data to load. As with the Well loader, you have the

option to save settings for future use. Be aware that Production imports are complete historical

replacements for each well.

IHS Production Data Types

A key point in loading U.S. production data is in understanding the difference between IHS

production data types. For reporting purposes, many states often roll up production to the Lease

level, rather than the Well level. To circumvent this reporting issue, IHS developed an allocation

process which takes all lease level production and applies it to individual wells. This technique

facilitates mapping individual well production by formation and study of individual well profiles.

The IHS allocation process incorporates well tests, allowables, and monthly status to apply the

lease level production to individual wells. Any lease level production with insufficient test data

for allocation to an individual well is designated as a Multi-well production ID, and may consist

of one or more wells’ production, possibly on adjacent leases. In this case, production is assigned

to the primary Multi-well API.

This procedure results in two types of production within the IHS database:

Allocated Production: These data have undergone the allocation process and are

currently available ONLY for Texas Oil and Louisiana Oil and Gas.

Unallocated Production: These data are reported “as is” (either lease level or well level)

from all states.

Both Production Types are available with your IHS Production subscription.

Production Import Scenarios

There are two main production import cases you might encounter with your PETRA projects,

based upon production type and project area:

1. Texas/Louisiana: for these wells you MUST choose either Allocated or Unallocated

production.

2. All Other States: for these wells Unallocated Production Only is the default option; no

selection is necessary.

NOTE: For projects covering multiple states, such as Texas, Louisiana, and Arkansas, you

only need to select the Texas/Louisiana production type since all other states default to

Unallocated Production. All production loads in one import for v3.6.1 or later.

Import Production from IHS Direct Connect Direct Connect to Well and Production Data

24 June 30, 2011

Allocated Production – Texas/Louisiana Only

This section describes the entire import process for the specific case of loading production data

into any project containing wells from Texas and/or Louisiana only. This example shows the

project used for the well data import which contains only Texas wells.

You launch the Production Loader from the Main module of Petra by selecting:

Project>Direct Connect>IHS US Enerdeq or Canada>Import Production from IHS

Direct Connect

NOTE: If this is your first time using the Direct Connect feature, you will be prompted for

your username and password. See Well Data section for more information.

The IHS (US) Prod Loader initial screen displays. Choose a well selection option to determine

the UWI list used for importing production data. An option to restrict by a date when updating

production is also available.

In general, use option 1 or 2 for your initial production import, since they use all or most wells in

your project. The last choice, I’ll Decide Later, gives you a chance to think about which wells to

select before you actually import the data. Select the Source menu to reactivate this screen.

Direct Connect to Well and Production Data Import Production from IHS Direct Connect

June 30, 2011 25

The optional date restriction for updates provides the same choices as in the Well Data Loader

and works the same way.

This example uses the 10180 wells selected in Main.

Clicking the OK button generates an immediate Enerdeq request for a list of production ID’s

(PID) for the wells in the UWI list, unless you choose the option I’ll Decide Later.

CAUTION: This request can take several minutes to complete. You will NOT be able to

cancel this request!

The Status screen displays the results of the PID search: of the 13,079 production ID’s selected,

10,773 will be used in this Texas Allocated import. This is the sum of Allocated PID’s (Oil) and

Well PID’s (Gas). The Unallocated (Lease) PID’s are not used.

At this point you proceed to the General tab and begin selecting parameters for import.


26 June 30, 2011

General Tab

This screen provides selection options for production streams and type.

Production Streams

This section provides choices for which streams are loaded; both options can be selected.

Load Production into Standard Streams (OIL, GAS, WTR, and DAYSON)

Check this option when you want to load data into streams called OIL, GAS, WTR, and

DAYSON. The cumulative values are stored in the WELL Zone as CUMOIL,

CUMGAS, and CUMWTR. Multiple producing formations are summed together.

Load Production into Individual Formation Names

Check this option to load data into separate streams by producing formation name. The

formation names are selected on the Formations tab. A stream code, such as O, G, W, is

appended to the formation name as a prefix or suffix to form the production stream and

zone item cumulative (total) names.


June 30, 2011 27

Texas/Louisiana Production Type

For projects with wells in Texas and/or Louisiana, you have to choose which production type to

load for those wells:

Unallocated Only – reported “as is” at well or lease level

Allocated Only – assigned to Well level via IHS allocation process

Production Stored As

This option provides selections for storing production as streams, CUMS, or both. Choices are:

Load Monthly Production Streams and CUM Values

Load Monthly Production Streams Only

Load CUM Values Only

Method to Apply Unallocated Lease Production to Individual Wells

This option is important when loading unallocated production from leases with multiple wells.

It determines how the lease production is applied to each well in the lease.

Load Production into First Well Only Listed in Lease – stores all lease production in the

first well on the lease; the remaining lease wells receive no production.

Load Production into Each Well in Lease (Subdivide) - total lease production is

subdivided equally among all wells in the lease (i.e., 6 wells in lease, each receives 1/6th

of total production).

Load Production into Each Well in Lease (Store Total) – All wells in the lease receive

the total lease production. May result in inflated production!

NOTE: This option is ignored when importing Allocated Only production.

Production Available to Load

This section displays the results of the PID query, as shown on the Status screen.

Fluid Types (Streams) to Load

This section determines which Standard streams are loaded, and which fluid types are loaded for

individual producing formations. Only the fluid types selected are loaded; uncheck all but OIL, if

you only want oil data loaded. Options:

OIL GAS WATER

DAYS ON WELLS ON Injection Data


28 June 30, 2011

Options Tab

This screen provides a variety of import options, as well as another chance to restrict the import

to a particular timeframe, if you did not choose this option on the initial screen.

Only Import Production Streams that have been Updated on IHS Server

This option is a repeat of that displayed on the initial screen; you can select the update method

here, if not chosen previously. Recall that PETRA saves the last import date in memory and uses

that when you select an option such as In the Last 2 Weeks.

Use the Get Counts button to check how many production ID’s (PID) would be downloaded.

MISC OPTIONS

This section provides various options for import. Check those of interest to you.

Load Production into INITIAL COMPLETION Wells Only

Select this option when you want to load production into “0000” wells only, for all wells

in the project. This restriction is accomplished by matching 10 or 12 digits of the API

number, as selected at the bottom of the screen.


June 30, 2011 29

Use INITIAL COMPLETIONS Only from Multi-Well Leases

Select this option when you want to load production into “0000” wells for only those

leases which contain multiple wells. This restriction is accomplished by matching 10 or

12 digits of the API number, as selected at the bottom of the screen.

Update OPERATOR and Save Current Operator as Historical Operator

This option assumes the production data Operator Name is the current operator for the

well. When checked, the existing operator name in your PETRA project is copied into the

blank Historical Operator field and replaced with the operator name from this import.

Update Well SYMBOL CODE from Primary Product Code

Select this option when you want to change the existing symbol code in your PETRA

project to the updated symbol based upon current production status.

Load Producing Fm Name into Well Header

This option updates the Producing Formation Name field in the Well Header with the

value from the production data import.

Store current STATUS in WELL Zone as PDSTATUS

This option stores the well status (Active or Inactive) in the WELL Zone as an item

called PDSTATUS.

Store GATHERER in WELL Zone as GATHERER

This option stores the gas gatherer in the WELL Zone as an item called GATHERER.

Store Production Tests in PdTest Table

This option stores all production tests in the PdTest tables in the database and displays

under the IP Tests tab.

Display Detail Info in Report

This option creates a detailed report of all monthly production values, which can be saved

in your project’s REPORTS folder.

Update Non-Blank Lease Number with UNIT WELL SERIAL NUMBER

This option replaces the non-blank Lease Number with the value of the Unit Well Serial

Number, if it exists. In some states this is a Permit number. If Unit Well Serial Number is

blank, it will replace the Lease Number with a null field.

Do not use “A” in prefix/suffix to designate Allocated Production

When loading Allocated Production, this option removes the default “A” prefix/suffix

stream code appended to the producing formation name on Totals and Formation tabs.

Use Digits for Matching Initial Well Completions

This option is used only in conjunction with the miscellaneous options for loading initial well

completions. It sets the API number of digits used to match with wells in your project.


30 June 30, 2011

Totals Tab

This screen controls where the Cumulative values for each producing formation stream are

stored, and how they are named.

Zone for Storing Formation Totals

Choose the Zone in which to store the Producing Formation totals, or use the New button to

create a new name.

TIP: For best results, always create a new Zone for storing these data rather than placing in

the WELL zone. It streamlines data management and project refresh rates.

Zone Items

This section contains a list of the Zone items and associated names. The first 4 items store the

cumulative values for Oil, Gas, Water, and Days.

When loading production by producing formation names, each stream has a production code

appended to the name as either a prefix or suffix, as selected on the Formations tab. The code

relates to the stream and type of production loaded. In this case:

AO = Allocated Oil AG = Allocated Gas AW = Allocated Water AD = Allocated Days


June 30, 2011 31

The next 3 items store additional miscellaneous information:

Lease Name: stores the text of the Lease Name in the item PRDLSNAME

Lease Well Count: stores the number of wells in the multi-well lease for the current producing

stream; relates to how the production data for the lease are subdivided.

Prod ID: stores the IHS production entity ID or PID text string.

Formations Tab

This tab is active whenever you select the option to Load Production into Individual Formation

Names on the General tab. It provides a listing of each producing formation name and a count of

the number of wells with that name.

Buttons

The All and None buttons allow you to either select all, or clear, the formation list. You can also

select specific names using either the Shift or Control keys.

Refresh with Translations button uses the translation operation selected on the Fm Subst tab.

Export Fm List button creates a file containing the information listed in the formation list box.


32 June 30, 2011

FM Name From

This option allows selection of the format for the producing formation name.

Fm Name Code: uses the IHS alphanumeric age and formation code, such as 403BCGM

or 354BRNT

Fm Name Desc: uses a descriptive code such as BEND CONGL or BARNETT/SH/

Fm Name Code (Age Only): uses the IHS age code only, such as 403 or 354

Reservoir Name: uses the reservoir name, such as BEND CONGLOMERATE GAS or

BARNETT SHALE

Prod Stream Name Qualifier

This option allows you to select the application of the stream code as a Prefix or Suffix.

Examples are AO_403BCGM for the prefix option and 403BCGM_AO for the suffix option.

CAUTION: Be consistent with selection of the Fm Name and stream qualifier formats.

Changing these formats for subsequent updates can result in duplication of production,

since producing names are unique to each import. For best results, you can save your

import settings and reuse them for updates; see later section for more information.

PdCum Tab

This screen provides options for storing production cum values in the Prod Cums table of your

project. Cumulative values are computed by summing the monthly production streams.

PD CUM TABLE UPDATE

This option controls how data are stored in the Prod Cums table.

DO NOT STORE in PdCum DB: no data are stored

STORE PdCum Data using ProdID as FmName: stores PdCum data, but also stores the

PID in the FmName field and the producing formation name in the Altname field. This

results in 1 Prod Cum entry for each PID.


June 30, 2011 33

STORE PdCum Data using ProdID as Altname: stores PdCum data, but also stores the

PID in the Altname field and the producing formation name in the FmName field. This

results in 1 Prod Cum entry for each PID.

STORE PdCum Data using FmName Only: stores PdCum data, but only the producing

formation name is stored in the FmName field; Altname field is blank. Multiple entities

for the same producing formation are summed.

PdCum Name Qualifier

This option allows you to add a qualifier to the producing formation name stored in the Prod

Cums table, as either a prefix or suffix.

Leases Tab

This screen controls which leases are used for the production import. The default is all leases.

Use the None button to clear the list. Use Shift or Control to select specific leases. The list

displays the lease name along with the well count for that lease.


34 June 30, 2011

P/Z Tab

This screen provides options for capturing the P/Z (compressibility) data streams for gas wells.

Load P/Z Gas Cum Data

Selecting this option activates the import options for loading this data.

Load P/Z Decline Data Into

This section contains the names for the P/Z data streams.

P/Z: creates a stream called PZ for the P over Z pressure

Gas Cum: creates a stream called PZGASCUM for the Gas volume from test

BHP: creates a stream called PZBHP for the Bottom Hole pressure


June 30, 2011 35

Fm Subst Tab

This screen provides a mechanism to change the names of the IHS formations using a name

substitution file. This file’s format follows the same rules as those described in the Well section.

The formation substitution file can be used to load several producing formation names into a

single entry in the project database. An example of the file format is shown above.

Browse to the file location so that the complete path appears in the field.

Use the Test Your Translations button to verify the file works correctly.

This file must be selected to use the Refresh with Translations button on the Formations tab.

Query Tab

This screen allows you to select a query from a list of your saved Enerdeq queries. You cannot

create any queries from this screen.

Click on the Retreive IHS Enerdeq Queries button to view your saved queries.

Select the query and click the Run Query button to use the query for well selection.


36 June 30, 2011

Save Settings

It’s a good idea to save your settings and load them when updating production. This ensures no

duplication of production by selecting different formation name formats or stream qualifiers.

Select File>Save Settings. Type a name that’s meaningful, such as Production Import Settings.

When updating production, select File>Load Settings; this restores current selections.

Status Tab

Click the Import Production button, click the OK button, and view the import progress on this

screen.


June 30, 2011 37

The system processes a batch of PID’s at a time until all production is imported. The time

required for import depends upon the number of wells and producing formations selected.

The completed import shows that production data imported for 7,700 wells, with total import

time about 32 minutes.

Save settings and close the IHS (US) Prod Loader screen. View the results in your project.

The examples below show results for WSN 18 (UWI = 42497000160000).

Unallocated Production – All US States

This section describes import options associated with loading Unallocated Production. Only

those changes specific to this import are described. See the previous section for discussion of all

import options.

NOTE: This is the default Production Type for projects with wells in any state(s) other

than Texas and Louisiana. It must be selected for Texas/Louisiana wells.

Getting Started

The example below uses wells from a project in Colorado.

Launch the US Production Data Loader from the Main module:

Project>Direct Connect>IHS US Enerdeq or Canada>Import Production from IHS

Direct Connect

Choose the appropriate well selection method for initial production import. In this case the wells

in Main are selected.

Click the OK button. View the Status screen for PID results and proceed to the General tab.


40 June 30, 2011

General Tab

Choose streams as described in previous section.

Note the following parameters:

Texas/Louisiana Production Type:

Notice that the field is grayed out, since all the wells are in Colorado. This occurs for wells in

any states except Texas and Louisiana. The NOTE indicates Unallocated Production as the

default.

Method to Apply Lease Production to Individual Wells:

Recommend Load Production into Each Well in the Lease and subdivide production by

number of wells in lease. This option stores an equal share of the total production among all

wells in the lease.

Production available to Load:

The results show 105 PID’s with 25 at the Lease level and 80 at the Well level. This information

can help you select the appropriate method for applying lease level production.


June 30, 2011 41

Totals Tab

Select parameters as noted in previous section. Select or create new Zone for storing individual

streams.

Zone Items

The item names are similar to those in the Allocated import, except the stream codes are O, G,

W, and D in the Unallocated Production import.

Remaining Tabs

Select all remaining parameters as described in the previous section under Allocated production.


42 June 30, 2011

Save settings for future use and then click the Import Production button.

The completed import processed 98 wells with production data in about 14 seconds. A WSN list

of updated wells was also created and stored for future use.

Close the Production Loader and view the results in the project for WSN 42.

IHS Production Zone: Shows individual producing formations and Lease Well Count of 3. This

means the production values listed for this well are 1/3 of the total lease level production.


June 30, 2011 43

Allocated and Unallocated – Texas/Louisiana and Other States

Use this import method for projects containing wells from multiple states including Texas and/or

Louisiana.

This example uses a project with wells in an AOI covering Arkansas, Louisiana, and Texas.

Since this project contains wells from 3 different states, there are 2 IHS Production Types

available for loading:

Unallocated Production for the Arkansas wells

Allocated Production for the Texas and Louisiana wells (must select)

Only those changes specific to this import are described. See the previous sections for

discussion of all import options.

Getting Started

1. Launch the IHS Production Loader by selecting Project>Direct Connect>IHS US

Enerdeq or Canada>Import Production from IHS Direct Connect

2. Choose the well selection option that works best for you. In this case the option Use the

1443 wells in Main module is selected.

3. Click the OK button and view the PID results on the Status screen. Proceed to the

General tab for parameter selection.


44 June 30, 2011

General Tab

1. For the Texas/Louisiana Production Type, select Allocated Only. The default of

Unallocated applies to the Arkansas wells. (See Note on screen).

2. Select the Method to Apply Unallocated Lease Production for the Arkansas wells. The

Subdivide Production among wells in the Lease is recommended.

3. Select other parameters as described in previous sections.


June 30, 2011 45

Options Tab

Select the miscellaneous options of interest and skip the Change Date section since this is an

initial production import, not an update.

In this example the option Do not use “A” in prefix/suffix to designate Allocated production

is selected. This selection simplifies the stream names and subsequent bubble mapping, by using

consistent stream codes for all wells.

Remaining Tabs

Select the parameters on the remaining tabs as previously described.

Save your settings, if desired, and then click the Import Production button.


46 June 30, 2011

View the results on the Status screen, close the Loader, and view the results in your project.

The results indicate that 631 PID’s were processed for 446 wells.

Best Practices

1. Be consistent with selection of producing formation names and stream qualifiers

(prefix/suffix) on import updates to avoid duplication of production. Use the Save/Load

Settings options.

2. Be consistent on the number of digits in your API numbers on import updates to ensure

production is stored with the same well. Again, using the Save/Load Settings options will

help for imports in which the Initial Completions only, and number of digits used to

match the API number, options were selected.

3. Create a Zone dedicated to storing individual producing formation CUMs and related

data. This action improves data management and project performance by not overloading

the Well zone.

4. Create a WSN list of all wells with monthly production to streamline viewing and

analyzing production data.

Import Options for Prior Versions of PETRA

The current document describes the Well and Production Import options available with PETRA

version 3.6.1. Not all these options are available in prior versions of PETRA. If you are currently

using version 3.4.x or 3.5.x, check here for sample screen shots and discussion, or better still,

update to the current version of PETRA.

Changes for Well Data Imports

The Well Data Loader has not changed significantly with PETRA version updates. The main

differences in the prior versions are:

Import Options>General Tab: fewer options available

Import Options> No Directional Survey Tab

No 297 File button

Changes for Production Data Imports

The most significant change in the current version (3.6.1) of the Production Data Loader is the

revision in selection of Production Data Type. The current version streamlines the import of

Allocated and Unallocated Production, especially in multi-state projects which include wells

from Texas/Louisiana.

In prior versions of PETRA, there were basically 3 Production Import Scenarios based on

production type and project area:

1. Single Import – Allocated Production: use this option when your project contains wells

from either or both Texas and Louisiana, but no other states. Since Texas Gas is reported

at the well level, this option imports all Texas production.

2. Single Import - Unallocated Production: use this option when your project contains

wells from 1 or more states, excluding Texas and Louisiana.

3. Dual Imports – Allocated and Unallocated: use this option when your project contains

wells from multiple states including Texas and/or Louisiana. For example, a project

covering Texas, Louisiana, and Arkansas. Use the Allocated Production type for the

Texas/Louisiana wells; then the Unallocated Production type for the Arkansas wells.

Sample screen shots and points to note for each of these scenarios, as well as other options, are

provided below.

Import Options for Prior Versions of PETRA Direct Connect to Well and Production Data

50 June 30, 2011

Allocated Production – Texas/Louisiana Only

This section describes specific parameters for loading production data for projects containing

wells from Texas and/or Louisiana only.

Only those parameters that differ significantly from those in the main body of this document

are shown.

General Tab

This screen provides selection options for production streams and type.

Production Type Loaded

The availability of this option is determined by which data are available. Currently, allocated

data are only available in Texas and Louisiana. The options include:

Unallocated Only – available for all states

Allocated Only – available for Texas and Louisiana ONLY

Direct Connect to Well and Production Data Import Options for Prior Versions of PETRA

June 30, 2011 51

Sum of Allocated and Unallocated – this option applied to Texas and Louisiana, but is

no longer necessary, as Texas Gas is reported at the Well level and imports via the

Allocated option; Oil and Gas are both allocated in Louisiana

Method to Apply Lease Production to Individual Wells

This option is important when loading unallocated production from leases with multiple wells.

It determines how the lease production is applied to each well in the lease.

NOTE: The NAME of this option changed in the current version. It always applied to

Unallocated Production only, and is ignored when importing Allocated Production.

Options Tab

This screen provides a variety of import options, as well as another chance to restrict the import

to a particular timeframe, if you did not choose this option on the initial screen.

Fewer options available!

The remaining tabs have no significant changes from current version.


52 June 30, 2011

Unallocated Production – Other US States

This section describes import options associated with loading Unallocated Production for

projects with wells in any state(s) other than Texas and Louisiana. This example uses a project

with wells from Colorado.

The only major change from the current version is on the General Tab.

General Tab

Production Type Loaded:

Notice that the field is grayed out – Unallocated Only is the only option available, since the

wells are in Colorado. This occurs for wells in any states except Texas and Louisiana.

Select all remaining parameters as noted in the previous sections.


June 30, 2011 53

Dual Production Imports– Texas/Louisiana and Other States

Use this import method for projects containing wells from multiple states including Texas and/or

Louisiana.

This example uses the same project with wells in Arkansas, Louisiana, and Texas, as described

in the previous section. Since this project contains wells from 3 different states, there are 2 IHS

Production Types available for loading:

Unallocated Production for the Arkansas wells

Allocated Production for the Texas and Louisiana wells

NOTE: The main change for this import scenario is that it requires 2 separate imports, 1

for each production type.

Pre-import Preparation

To streamline your workflow before importing production, you should create the following:

1. WSN list containing the wells for the Unallocated Production import. In this case the

list contains Arkansas wells only.

2. WSN list containing the wells for the Allocated Production import. In this case the list

contains Texas and Louisiana wells only.

3. New zone for storing individual producing formation cumulative values.

NOTE: If you prefer to skip these steps, you can use the Search Wells by Data Criteria

option for well selection, and create new zone option on the Totals tab.

First Import

Decide which production type you plan to import first; there is no priority to the order. In this

example the Allocated Production is loaded first.

1. Select the WSN list for the Allocated Only import – the Texas/Louisiana wells. This

reduces the well list in Main to just those you need for this import. This step is optional,

but recommended for efficiency.

2. Launch the IHS Production Loader by selecting Project>Direct Connect>IHS US

Enerdeq or Canada>Import Production from IHS Direct Connect

3. Choose the well selection option that works best for you. In this case the WSN list is

already selected, so the option Use the 1136 wells in Main module is the best choice.


54 June 30, 2011

4. View the PID results on the Status screen. In this example there are 938 total PID’s; 513

allocated, 307 unallocated, and 118 well. Therefore, 631 PID’s will be imported:

allocated + well.

5. On the General tab, for Production Type Loaded, select Allocated Only. Choose other

options as applicable. Recall that the Method to Apply Lease Production is ignored when

importing Allocated Production.


June 30, 2011 55

6. On the Options tab, select the miscellaneous options of interest and skip the Change Date

section since this is an initial production import, not an update.

7. On the Totals tab, select the zone for storing the individual producing formation stream

cumulative values and the items to store. In this example the data are stored in the IHS

Production zone. The streams use the AO, AG, AW, etc. codes to indicate allocated

production in your database.

8. On the PdCum tab, select STORE PdCum Data using ProdID as Altname and use A

as the PdCum Name qualifier. This helps in identifying which PID’s relate to the

allocated production import. (The qualifier is optional).

9. Make your selections on the remaining tabs. Save settings, if desired, and then click the

Import Production button.


56 June 30, 2011

10. View the results on the Status screen, close the Loader, and view the results in your

project.

Second Import

Once the first import is complete, you launch the importer for the second import, in this example

Unallocated Production.

1. Select the WSN list for the Unallocated Production import. In this example the list

contains 307 wells from Arkansas.

2. Launch the IHS Production Loader as in step 2 of previous section and select the wells

for import. In this example, the 307 wells are already selected in Main, so that’s the

option selected.

3. View the PID search results on the Status screen. In this example there are only 54 total

PID’s: 0 allocated, 52 unallocated, and 2 well.


58 June 30, 2011

4. On the General tab, select the Method to Apply Lease Production, in this case the

Subdivide option, and all other parameters of interest. Production Type Loaded

(Unallocated) is grayed out, as there is no other option.


June 30, 2011 59

5. On the Totals tab select the zone for storing the totals, in this case IHS PRODUCTION.

Notice that the stream codes are O, G, W, etc. This differentiates these producing

formation streams from the allocated streams.

6. Make selections on the remaining tabs as previously described. Save the unallocated

settings, if desired. Click the Import Production button, view the results on the Status

screen, and then close the Production Loader.

The results show that 54 PID’s were processed for 47 wells.


60 June 30, 2011

The production results for an Arkansas well: WSN 70 (UWI = 03091009630001)

IHS PRODUCTION Zone

Prod Cum – (A qualifier of U for Unallocated was used)

Once both production imports are complete, you might want to create another WSN list of all

wells with monthly production, to streamline viewing and analyzing production data.
