Drilling permit application type
rrc.application_type
What the operator asked permission to do. A single wellbore accumulates several of these over its life: an original DRILL, then a RE-ENTER or a PLUG-BACK years later. The pipeline that loads this data resolves the code on the way in, so the warehouse column holds the text below rather than the raw RRC code. Both are recorded here so the original filing can be read either way.

Columns that use these codes
| Dataset | Column | Meaning |
|---|---|---|
| Drilling Permit Master | application_type |
What the operator asked permission to do, as the RAW two-digit code: 01 drill, 05 other, 07 re-enter, 09 field transfer, 14 recompletion, 15 reclass are the six the current file uses, and rrc.application_type documents all fifteen the layout defines. Nothing decodes this on load, unlike texas.permits. |
| Drilling Permit Master and Trailer | application_type |
What the operator asked permission to do, as the RAW two-digit code: 01 drill, 05 other, 07 re-enter, 09 field transfer, 14 recompletion, 15 reclass are the six the current file uses, and rrc.application_type documents all fifteen the layout defines.
