Importing Well Production Data from a General Format User File or VOL File

In document SCUA-GOCAD Import-Export.pdf (Page 99-105)

You can use the General Format import wizard to import production data from column- based user files and VOL1 files. The command adds the data to existing Well objects.

Note The format of VOL files is not strictly column-based. The well name is on a row by itself, and

the production data for that well is in column format following the well name. The converter reads the columns of data for the first well until it encounters the next well name on a row by itself, and then begins reading the columns for this well.

This wizard includes many settings that are common to other column-based import wizards. This topic describes only the steps that are specific to importing production data. For information about how to configure the common settings, see "Common Process for Importing a Column-Based File" on page 1-8.

Tip For production data, specifying a no-data value of -99999 prevents null data from appearing as

zeros in production plots. For information about how to specify a no-data value in the wizard, see

step 6 in "To specify the column assignment for a column-based file" on page 1-12.

For more information about importing production data, see:

"To access the import wizard for column-based production data," page 1-91

To access the import wizard for column- based production data

Select File > Import > Well Data > Production Data > General Format User File to open the Column as Production Data - General Format wizard.

To specify the production data type and scenario

After you access the Column as Production Data importing wizard and complete the common settings on the first pages (see "Common Process for Importing a Column-Based File" on page 1-8), specify the type of production data that you are importing and the scenario as follows:

1 Ensure that the file you want to configure is selected in the Current file box.

2 Specify whether you are importing historical data by selecting or clearing the Historical production data check box, and then do the following as necessary:

If you specified historical data, you do not need to define a scenario for this data, because the command imports historical data into the Project (root) scenario.

If the production data is not historical, specify the scenario by doing one of the following:

To use the file name to identify the scenario, click Use filename.

To provide a name, click Select or type it, and then enter a unique scenario name in the box.

To specify a line in the file that identifies the scenario, click Select line, and then type the line number in the box, or click , and then click the line in the preview pane.

The scenario name is useful, for example, to help you differentiate between multiple sets of production data.

3 Click Next. To specify the date

format

Specify the date format of the production data as follows:

1 For the question What is the type of your dates?, click either:

Date value. Time is given as a date.

2 Depending on the date format selected, specify additional information about the data as necessary:

3 Specify the type of production data, unit system, and object type as follows:

4 If you want to import production data only for existing wells, ignoring any additional production data for other wells, select the Load only on existing objects check box.

5 Click Next.

Setting Description

Elapsed time unit The time is given in years, days, hours, minutes, or seconds.

Date format Click either One column (if the date or time is given in a single column) or Multiple columns (if the date or time is given in multiple columns), and then select the date format for the time or the start date.

If you select multiple columns, later in the wizard, on the Line and Column Assignment page, you can specify what each column represents.

Start date The start date of production (for example, 01/01/1983).

Tip Change the date by highlighting the month, day, or year in the box, and then increase or decrease the number with the buttons.

Setting Description

Data type The data includes daily rates, interval volumes, or total volumes. Units system The data is given in field, ECLIPSE-metric, or metric units.

1.14 Importing Well Data 1-95 User Guide

To specify the phase

units

On the Selection of the phase units page, the units for each value are preselected based on the Units system selected on the prevous page in the wizard. Change the units for any production value as necessary (following the instructions in the wizard), and then click Next.

To specify line and

column assignments 1 On the Line and Column Assignment page, assign each type of data to the appropriate column in the file (following the instructions in the wizard), and clear the check box for any data that is not included in the file.

Notes

• If you indicated that date or time values are given in multiple columns, this page has additional options for indicating which columns represent each part of the date or time value (For example, Day column, Month column, and Year column).

If you are importing a VOL file, Well or Group name column is not available (appears dimmed). In VOL files, well names are on rows by themselves (not in columns), and the converter finds the well names automatically.

The Days produced column should specify the number of days of actual well production during the specified period. If you indicate that you want to compute missing production data (see step 2), this number affects the daily production rate calculation. For example, if production is not a full month, you need to specify the number of actual producing days.

Tip If you calculate this data, you can display it as bubble maps for the wells in 3D and 2D views. For more information, see Part III: Visualization, "Displaying Production Data as Bubble Maps" on page 3-21.

2 If you want to calculate any missing production data, select the Compute missing production data check box.

Depending on the type of production data (cumulative volumes, production rates, or interval volumes), the command can calculate:

Production rates from cumulative or interval volume

Cumulative volume from production rate or interval volume

3 When you finish specify the column assignments, complete the steps in "To complete the importing process" on page 1-14.
