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.
