The Geographix Depth Registration ASCII file is paired with a .TIF image file and is used in Strater to create registered raster logs with the Log | Create Log | Registered Raster command.
The DRA file is a comma delimited ASCII file with six record types. Each record is on a separate line limited to 256 characters. Text strings with blanks or commas are enclosed in quotes. The DRA file records contain file, well, log, depth calibration, curve scales, and log header information. The first record is the File Header record (FILE) followed by information for one or more wells. Each well begins with the Well Header record (WELL) followed by one or more Log Section records (LOG) each log section may have a Curve Insert record (CURV), a Header record (HEAD), and multiple Depth Calibration records (DPTH).
The following table includes the record types and the comma delimited values for each record.
