You can use the ECLIPSE column-based import wizard to import production data from ECLIPSE files and add the data to existing Well objects.
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
"To specify the column assignment for a column-based file" on page 1-12.

You can easily import ASCII historical data by using the column-based importing wizard as follows:
•
Identify the columns that contain standard ECLIPSE data keywords followed by "H." For example, historical field oil-production data becomes FOPRH; similarly, historical well water-cut data becomes WWCTH. For a list of the most common ECLIPSE keywords, see Part X: Reservoir Production and Simulation, "Primary ECLIPSE FrontSim production data" on page 5-13.•
Identify the units in the historical data by using these unit identifiers:•
Pressure. barsa and psia•
Rates. sm3/d, stb/d, and Mscf/d•
Ratios. sm3/sm3, Mscf/stb, and stb/stb•
Identify the objects by these names: FIELD, WELL, or GROUP.The following is an excerpt from a comma-separated values (CSV) file containing historical field data: DATE,FPRH,FWPRH,FGPRH,FOPRH ,barsa,sm^3/d,sm^3/d,sm^3/d ,FIELD,FIELD,FIELD,FIELD 1/1/1988,397.8,0.0000,0.0,0.00 1/1/1989,307.6,0.0000,1356750.0,9000.00 1/1/1990,233.7,0.0000,1217807.5,9000.00 4/1/1990,221.9,0.0000,1183632.1,9000.00
In this example, the first line identifies the ECLIPSE data types with an "H" to indicate historical data. The second line identifies the units for each data type, and the third line indicates the object, FIELD. The data is delimited by commas, with the date in the first column followed by pressure, water production rate, gas production rate, and oil production rate.
To access the import wizard for ECLIPSE column-based production data
Select File > Import > Well Data > Production Data > ECLIPSE User File to open the Column as Production Data - ECLIPSE format wizard.To specify the production data type and date format
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 date format as follows:
1 Ensure that the file you want to configure is selected in the Current file box.
2 For the question What is the type of your production data?, click one of the options: Historical or ECLIPSE name convention.
Note If the production data names have an "H" at the end of the string (FWPTH, for example)

3 For the question What is the format of your dates?, click either:
•
Date value. Time is given as a date.•
Elapsed time value. Time is given as years, days, hours, minutes, or seconds. 4 Depending on the date format, specify additional information about the data asnecessary:
5 Click Next. To specify the
production scenario In the Column as Production Data import wizard, specify the scenario as follows:Note This page appears only if the file does not contain historical data. If the file contains historical
data, the command automatically imports the data into the Project (root) scenario. You cannot specify a production scenario for historical data.
1 Ensure that the file that you want to configure is selected in the Current file box. Setting Description
Elapsed time unit The time is given in years, days, hours, minutes, or seconds. Date format The date format for the time or the start date.
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.
2 Name the production scenario as follows:
•
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 The scenario name is useful, for example, to help you differentiate between multiple sets of production data.Click Next.
