About this data
Registration from the RRC P-5 organization report, refreshed weekly. 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.
