1 Module Brief Introduction:

FieldAssist is developed to do well performance evaluation. The module will read well

equipment, trajectory, reservoir and production data to plot wells over a pre-stored evaluation

template. Then, give results to show the number of wells located in different performance criteria.

The user is also able to create self-defined template for evaluation.


4

2 About this Training Material:

The purpose of the training is to give a guide about the procedure to perform basic

functionality of the module. After finishing the training, the user should be able to define

performance evaluation templates for rod pump and ESP and perform well performance evaluation.


5

3 Performance Evaluation for Rod Pump:

3.1 Template Creation:

Before we initiate a performance evaluation, we can first finish managing the template we

need. When we open the module, the menu bar shows we can create two types of templates-Pwf

vs. Pump Eff., Inlet Pressure vs. Pump Eff.

We click to open the “Pwf vs Pump Eff.” type template setup interface. The menu bar of

the “Operation” enables the user to import/export template, check template information, etc. The

“Parameters Input” panel shows all necessary manual input data to construct a template. The right

side result panel shows created template.


6

We can see that the template is just a plot that divides the Pwf vs. Pump Eff. plot or Pwf/Pb

vs. Pump Eff. into several performance areas. Module has already provided a set of default data

for a template. We can directly use the default data.

The user can switch between two types of templates (Pwf, Pwf/Pb) by clicking the icons on

the menu bar. In this case, we click the Pwf type template.

Then, our template will look like the figure below:

Then, we can click to export the template as a file on the PC. A window will pop up

to let the user select a path. We name the file as “Self Template”. We select “Save” to store the

file on PC. The template file is in .rpt format.

Next, we can click to open the template creation interface for the second type of template.

The setup and export procedure is totally same as the first type. The document will only introduce

some data that needs to be input manually.

3.2 Performance Evaluation:

Since we have the template, next step is to initiate performance evaluation. In this part,

database data is needed.

We can click to open the function interface. The function jumps to the table interface

automatically to show what data will be needed to do the evaluation. On the menu bar under the

“Operation”, the user can import database data and template as well as do the calculation.

We first click “Load Data”. Choose the “OPT” reservoir and select all wells in the reservoir.

We choose “Daily” as our analysis period. We can just use the default setting for the database

and Prod. Date. Finally, we click “OK”.

Data are uploaded from the database to the function:


14

The document will introduce necessary data by data tables with the minimum data needed to

run the function:

Production Data-

Database table that contains the data:

Notice: Since the DemoData database has too much production data, several pages of table

are filled. The production data for other wells are stored in other pages of the table.


15

Then, we need to select a template. We can either select a template already stored in the

module library, or select a template file we just saved. In this case, we select a template file we

just created. We click “Import Template” and choose “Template File”.

A window will pop up to let us select a file. We choose the “Self Template2” we just created

and click “Open”.


16

We will see the template in the result panel:

Finally, we click to generate results.

Function Results:

Function will evaluate all wells and put them over the template to demonstrate the

performance of each well. Evaluation summary and result tables will also be provided with

statistical analysis to give the user a better view about the performance condition of a reservoir.

4 Performance Evaluation for ESP:

4.1 Template Creation:

FieldAssist also provides 2 types of template for ESP-Pump Inlet GLR vs. Discharge Eff.,

Inlet Pressure vs. Discharge Eff. The setup procedure is same as that in the rod pump. Therefore,

only data needed by the feature will be introduced.

We click to enter the template creation interface. The template parameters are all

input manually.

4.2 Performance Evaluation:

Since we have the template, next step is to initiate the performance evaluation. In this part,

database data is needed.

We click to enter the evaluation interface. We click “Load Data”. Choose the “OPT”

reservoir and select all wells contained in it. We set the production date as “12/31/2011” and

choose “Daily” as our analysis period. We use the default database setting and click “OK”.

Available data will be shown in the result panel.

The document will introduce necessary data by data tables with the minimum data needed to

run the function:

Production Data-


27

Database tables that contain the data:

Notice: Since the DemoData database has too much production data, several pages of table

are filled. The production data for other wells are stored in other pages of the table.

Then, we need to select a template. We can either select a template already stored in the

module library, or select a template file we just saved. In this case, we select a template file we

just created. We click “Import Template” and choose “Template File”.

A window will pop up to let us select a file. We select the “Self Template ESP2” we have

created.

The template will be shown in the result panel.

Finally, we click to generate results.

Function Results:

Function will evaluate all wells and put them over the template to demonstrate the
