• Each Petra "project" is a semi-structured collection of E&P assets that interoperate with its own DBISAM database. From an IT perspective, Petra is a distributed collection of user-managed databases "on the network" containing millions of assets.

WHO IS THIS FOR?

This was developed as part of a Databricks geospatial catalog pipeline. It is useful for quickly exporting data from Petra, particularly if you don't have a license or want to avoid Petra's cumbersome ASCII export.

LIMITATIONS:

If you are trying to egress lots of data from a large Petra project, this is NOT the tool for you. It relies solely on ODBC via Python. You are better off exporting/parsing a .PPF file.

purr_petra_cli should be fine for smaller projects ~ roughly those with < 100000 wells. Use the --uwis filter to limit state/county. It's slow but memory-safe.

QUICKSTART:

1. pip install purr_petra_cli
2. launch console "as Administrator" and run prep-purr-petra
3. start-purr-petra
