Geolog 6.6 - Connect Tutorial Introduction 1

Introduction to Geolog's Connect Tutorial

Welcome to Geolog’s Connect tutorial.

This tutorial is designed for new users of Paradigm’s Geolog Connect product, and for users familiar with Geolog’s Load/Unload products, which Connect now replaces. You will learn the basics of using Connect through a typical workflow and procedures to:

• Perform a typical data load

• Perform various data loads using different file formats

• Perform data unloads using different file formats

• Perform file transfers such as project to project and from one format to another

Prerequisites

The Geolog Basics tutorial and a basic knowledge of industry data formats is advantageous.

Document Conventions

In this document, all INPUT to the computer is in Bold Courier New, while all OUTPUT from the computer is in Courier New, but not bold.

Tutorial Data

The following additional files (files not supplied with software) are used in this tutorial:

paradigm.unl is located in the installation directory. A second project, MOONS (moons_master.unl), is used for the Project to Project transfer exercise.

Geolog 6.6 - Connect Tutorial Connect Overview 2

Connect Overview

Geolog’s Connect application replaces the Load/Unload applications in Geolog6.16 and earlier versions. Connect also provides new functionality not available in previous Geolog versions. Unlike some of Geolog’s applications, Connect is not an MDI (multiple document interface) application.

Connect can be used to perform the following tasks:

• Load data to a database

• Unload data from a database

• Transfer data between databases (projects)

• Transfer data between contractor formats

Data Format

A wide range of industry standard formats (both binary and ASCII) can be accessed using the Connect application:

Data Sources:

Binary Format LIS, DLIS*, Western Atlas BIT, Century, BPB, SEG-Y, ELF FIMAGE, RMS, Amoco-A, Zycor ZMAPNote: *DLIS is an optional module

ASCII Format LAS, Geolog-ASCII, User Defined Flat ASCII

Geolog Projects: Directly from other databases (via the well data server) which may be, for instance, Geolog, OpenWorks or Geoframe.

Disk: Files on local hard drives in either their native file format or in Tape Image Format (TIF).

I/O devices: Standard input/output devices can be used to read or write data. Common devices include CDROM, floppy, EXABYTE tape, 9-track, and DAT Tape. The setup of these devices is covered in the Geolog Site Administration tutorial.

Networks: Files located on networked disks, remote disks, and devices via dial-up, or VPN.

Starting Connect

1. Start Geolog and open the STARS project.

2. To start the Connect application perform one of the following:

Click Connect on Geolog’s Launcher Bar.

OR, to start Connect independently:

• in a UNIX / DOS window, change to the project directory, if required, and then enter the following command:

% geolog6 mui_connect &

• from a Tcl shell (select Project > Terminal(Shell)... on the Launcher Bar) change to the project directory, if desired, and enter the following command:

% mui_connect &

to display a window similar to that shown in Figure 2.

Exercise 1

Message Log

After Connect is started, all error and warning messages are logged to the Message section at the bottom of the Connect window.

The More Info icon can be selected at any time during scanning or loading/unloading/transferring to display the Feedback window which shows detailed message information (see Figure 3).

In order to obtain a more complete listing of all diagnostic and error messages, redirect them back to the Feedback window by setting the environment variable. This can be done before launching Connect or from the Run command (Connect > Run...) as follows:

• UNIX: c-shell (csh):setenv MIN_FEEDBACK debug

• UNIX: korn shell (ksh):setenv MIN_FEEDBACK=debug; export MIN_FEEDBACK

• Windows 2000/XP:tcl shell (tcl): set env(MIN_FEEDBACK) debug

Geolog 6.6 - Connect Tutorial Step 1: Load Data 6

Step 1: Load Data

Procedure

In this step, a typical data load procedure is outlined.

Overview

Connect’s Load function enables users to import data from various sources into a Geolog or other recognized database. The Load function requires minimal user interaction because of the following features:

• Automatic detection of incoming data formats. The following formats can be loaded using Connect:

• Data can reside on various forms of media (e.g., on a network, on tape, or in a file).

• The load operation automatically translates contractor mnemonics and converts units, if required.

• User defined ASCII formats need to be set only once and, from then on, are recognized as a standard format.

A Load dialog box controls all aspects of the load procedure (input type, limits, set/log skipping, name changes, reporting specs). However, for a basic load, it is a simple matter of:

• Entering the filename of data you wish to load.

• Clicking Start Load. Geolog handles the rest.

• Amoco_A • Geoshare (for third party product data exchange)

• Atlas (Western Atlas BIT) • LAS• BPB • LIS• Century • RMS• DLIS • SEG-Y• ELF FIMAGE • User Defined Flat ASCII• Geolog-ASCII

www.fanarco.net


A Typical Load Procedure

• Select Connect > Load... to display the Load Scan dialog box.

• Click the File Select icon next to the Device/File field to open the File Select dialog box.

• Locate and select the input source (project, file, tape, network).

• Define formats, translations, conversions, stats, reports.

• Click OK to scan the file.

• Fine tune your selection, narrowing it down, using the Connect window, to only those sets, constants, logs, ranges required (see Figure 4).

www.fanarco.net


• Click Start Load to begin loading the data.

Geolog 6.6 - Connect Tutorial Step 6: Batch Data Loads 38

Step 6: Batch Data Loads

Procedure

This step explains how to load data using batch methods.

Batch Data Load Controls

Most of the Geolog6 facilities can be driven from external batch style commands. Enabling other applications to access the database, display logs, build sections, or process data. For the Connect application, the log_load_batch script permits multiple files to be loaded without the interruption of the graphical user interface. Files such as LIS, TIF or LAS can be loaded into the database following the standard name_translation and well identifier style.

• Name mapping is controlled by.names files.

• Primary Well Unidentified is controlled by geolog6.defaults.

Defining an Alternative Well IdentifierTo set your primary well identifier to be API (or another primary well key), simply add the statement: PWI = API to the geolog6.defaults file in the project or site specs directory. Ensure the expressions match the name of the field in your file.

log_load_batch

"name_translation" in the following examples is an optional parameter.

OUTSIDE the Geolog environment:

• Start a Unix shell.

• Change to the project directory.

• Enter:geolog6 log_load_batch file_in = ./data/*.las name_translation=las

www.fanarco.net

Geolog 6.6 - Connect Tutorial Step 6: Batch Data Loads 39

WITHIN the Geolog environment:

• From the Geolog Launcher Bar, select Project > Terminal (Tcl). This opens a Tcl terminal window with the Geolog6 environment set for you.

• When running on either Windows or Unix, enter:

log_load_batch file_in=[glob ./data/*.las] name_translation=las

OR

• From the Geolog Launcher Bar, select Project > Terminal (Shell).

• When running on Unix, enter:log_load_batch file_in = ./data/*.las name_translation=las

If you prefer to use the GUI interface, you can concatenate files of the same contractor type (e.g., all las files) into one file and then load the concatenated file using Connect.

For example:.

Then start Connect and load bigfile.las

Note: Ensure you have sufficient disk space before concatenating the files and consider archiving/deleting the concatenated file when the load is complete.

Geolog 6.6 - Connect Tutorial Step 7: Unloading Data 40

Step 7: Unloading Data

Procedure

This step explains how to unload data from Geolog or compatible databases to various file formats. You will:

• Unload well data in Geolog-ASCII format.

• Unload well data in LAS format.

Overview

Connect’s Unload function has the following features:

• A variety of standard contractor, user defined and Zmap formats.

• Unload selectivity, ensuring only data needed and the depth interval required is unloaded.

• Data unload to diverse sources: files (local or from network), TIF (tape image format), and tape (magnetic 9-track, EXABYTE, DAT).

• Automatically translates contractor mnemonics and converts units.

Connect’s Unload function controls all aspects of the unload procedure. The format of this function is consistent with the Load function except the Unload function requires wells to be selected from the Geolog database.

www.fanarco.net

www.fanarco.net


7. Click OK. Geolog interrogates the database and display the FILES table with all well.sets to be unloaded (see Figure 33).

Geolog is now ready to unload all the data from the 3 wells into a single ASCII file (threestars.dat). This file is saved to the project’s data directory.

8. Click Start Unload to initiate the Unload.

Messages on the unload progress are displayed in the Message Area.

9. Leave the Connect window open to continue with the next exercise, Exercise 2.

Figure 33: Unload Window after Scanning Data

www.fanarco.net


Unload LAS Format Data

Data can be unloaded to either LAS Version 2 or Version 3.

LAS Version 2

1. In the Connect window still open from the previous exercise, Exercise 1, select Connect > Unload… to display the Unload Scan dialog box.

2. Change the Contractor format to LAS2.

Geolog sets the Name Translation to las automatically, and also resets the output file name to {well}_{set}.las, which makes it easy to store data from each set into individual LAS files.

3. Leave the default file name of {well}_{set}.

4. Click OK to view the list of logs and sets in the wells.

5. Middle click on the Use column header (on the word "Use") to deselect all.

6. Click in the Use checkbox to select the WIRE data () for each well.

Exercise 2

www.fanarco.net


7. Toggle on the LOGS table, and in the FILES table, for each well (ATLAS, BOTEIN, AND CAPPELA):

— click on the well row containing the WIRE data, then

— change the Name to Use, for GR_1, from GR to GR_COR (see Figure 34).

8. Click Start Unload to unload the data.

www.fanarco.net


LAS Version 3The following table explains the differences between the LAS 2 and 3 formats:

Figure 35 shows the resulting output of both formats using the default file names.

LAS VERSION 2 LAS VERSION 3

The output file is SPACE delimited. The output file is COMMA delimited.A file name of {well}.las produces ONE LAS file PER WELL that is being unloaded. Each file is identified by the well name and contains multiple sets.

The default file name, {well}.las, produces ONE LAS file PER WELL that is being unloaded. Each file is identified by the well name and contains multiple sets.

A file name of {well}_{set}.las produces ONE file PER SET (e.g., well1_wire.las).

If a file name of {well}_{set}.las is used, the output is the same as above.

If any other name is used, ALL the chosen wells/sets are unloaded into that single file.

If any other name is used, ALL the chosen wells/sets are unloaded into that single file.

Geolog 6.6 - Connect Tutorial Step 8: Transferring Data 48

Step 8: Transferring Data

Procedure

This step explains how to transfer data between projects, or from one file format to another. You will:

• Transfer data from one project to another.

• Transfer data directly from LIS format into a user defined flat ASCII format.

Project to Project Data Transfer

Connect’s Project to Project function transfers data from one Geolog or compatible database/project to another Geolog or compatible database/project. The application has the following features:

• Direct transfer of data between projects.

• No need for intermediary files.

• Data can be transferred from a Geolog database to another database such as OpenWorks or GeoFrame (or vice versa).

www.fanarco.net


In this exercise you will transfer some of the data from a single well in the STARS project to the MOONS project.

1. Select Connect > Project to Project… to display the Project to Project Scan dialog box (see Figure 36).

2. Ensure the Input Project is STARS.

3. Click the Well Select icon to display the Select Multiple dialog box.

4. Select ELECTRA, click the right arrow button to move the well into the Selection list, and click OK.

5. Leave the "Prevent Overwriting By" defaults. See "Prevent Overwriting Options" on Page 51 for an explanation of these options.

6. In the Output section, click the Project icon to display the Project Select dialog box.

Exercise 1

Prevent Overwriting Options

File to File Data Transfer

Connect’s File to File function transfers data from one contractor format to another contractor format. The module has the following features:

• Direct transfer of data between formats.

• No need for loading of data into Geolog.

• Data can be transferred between any of the known contractor formats.

• Data transfer can also be done between diverse sources/targets: files (local or from network), TIF (tape image format), and tape (magnetic 9-track, EXABYTE, DAT).

In this exercise you will transfer data directly from LIS format into a user defined flat ASCII format.

1. Select Connect > File to File… to display the File to File Scan dialog box (see Figure 38).

Renumbering Sets

If sets with the same name exist in the source and destination projects, a new and unique set name is constructed for the destination project. The set name created is suffixed by "_n", where n is either 1, or 1 more than the original destination set name suffix.

Reversioning Logs

If sets with the same name exist in the source and destination projects, logs from the source project are copied to similarly named sets in the destination project, but do not overwrite existing logs as they are created bearing an incremented version number.

Exercise 2

www.fanarco.net



3. Locate and select the schlum_lis.tif file as the input file, and click OK.

The header of the file is automatically scanned, and its type and appropriate name translation is determined by Geolog to be LIS.

4. In the Output section, select FLAT ASCII as the Contractor Format.

5. Click Define... to open the Flat Ascii window so you can create the new definition.

You may recall (from "Load LIS Data" on Page 9) that the input file contains only one set of data which has the following logs in it: DEPTH, GR, LLD, LLS and MSFL. In this exercise, we want to transfer all these logs to an ASCII format file.

Figure 38: File to File Scan Dialog Box

www.fanarco.net


6. Create a flat ASCII definition as shown in Figure 39.

Use the Table Menu icon to insert rows.

7. Save the specification.

8. Close the Flat Ascii window.

9. Check the Flat Ascii Format field specifies deep_logs.

10. Change the Device/File output name to deep_ascii.dat.

11. Click OK to scan the original file and display the data to transfer.

12. Change the name of the set in the Deep_#1 well to be WIRE.

13. Toggle on the LOGS table to check the logs that are to be transferred.
