Step 2: Setting up reading parameters

Step 3: Checking reading parameters

Click on Parsed file tab to check if you set reading parameters correctly and also you can decide which columns you want to add or skip:

Under Fields connections, use each drop-down to map a source column or choose Skip.

The well Type and Status are handled as two separate field connections. If your source file already contains columns named Type and Status, g-Space matches them to these fields automatically while loading the data.

Importing well headers from Petrel format

Besides plain text and CSV files, g-Space can read well headers directly from a Petrel well head export. In Data Manager, right-click the Wells folder, open Import, and choose Well headers from Petrel.

In the file dialog select one or more Petrel well head files (*.txt, *.dat) and set the coordinate reference system (CRS) and measurement system for the imported data.

A Petrel well head file declares its columns inside a BEGIN HEADER ... END HEADER block, with one column name per line; the well data starts on the line after END HEADER. g-Space recognizes the standard Petrel columns and maps them to well header fields:

  • Name – well name
  • UWI – unique well identifier
  • Surface X, Surface Y – well head coordinates (required)
  • Well datum name, Well datum value – Kelly bushing (KB)
  • TD (MD) – total depth
  • Spud date – completion date
  • Operator – company name

Note

Surface X and Surface Y are mandatory. Any additional columns found in the header block are imported as extra well attributes.
