RRC lists no operator of record

A well's operator of record is the RRC's, and its permit operator is the one on its latest drilling permit; neither fills in for the other. Its wellbores of record are counted as its wells, with its live permits; a well it permitted that another operator runs, or that the RRC lists with no operator at all, is not. Each count opens the wells it counts. Transfers and operator numbers →

About this data

Permits from the OGA049M master and daily daf420 files; wells of record from the EWA wellbore schedule; production from PDQ lease reports by the operator that filed them, through the statewide reported-through month; disposal from UIC permits and H-10 reports. Oil includes condensate from gas leases and gas includes casinghead gas from oil leases, as the RRC totals them. Summary figures are rebuilt nightly. Nothing is estimated.
