About this data

Field 77308300 from RRC PDQ lease reports: lifetime totals and lease and operator counts from the field summary; the monthly series summed from every lease report naming the field, cut at the statewide reported-through month, Aug 2026. Oil includes condensate from gas leases and gas includes casinghead gas from oil leases, as the RRC totals them. Counties from the wells completed on each lease. Completions are the wellbores the RRC schedule ties to the field. The formation, Marble Falls Zone 5, is read from the field's name. Nothing is estimated.
