Elevation translation codes |
|
The datum of a well can be important for accurately estimating subsea depths. There are a few standard codes for the different elevation measurements, such as:
Petra can correct for non-standard elevation codes during import with an elevation code translation file. An elevation code translation file lists the standard elevation codes followed by the non-standard variations reflecting the same actual elevation. As an example, listing GR with the variant GL will change all GL to GR thus importing the datum value correctly into Petra. Importantly, any name not translated by the substitution file will remain as is, and wont necessarily be recognized by Petra as a reference datum. Substitution files are a simple text ASCII file that can be created with a simple text editor. The file consists of a list of preferred names followed by the variants of that name. Every line has a prefix of 1 or 2, where "1" represents the preferred name and 2 represents the variants. For example:
