Matagorda County · Northern Ranch (Robertson Sand) field · Vertical
Northern Ranch #4 (API 42-321-00023) is a permitted well in Matagorda County filed by Apache Corporation; no completion report is on file yet.
The RRC has issued 3 drilling permits (amended once) between 1978 and 2010, permitted to 7,516 ft.
It was permitted by Apache Corporation and has since transferred to Cockrell Oil Corporation on the wellbore schedule.
Its 4 leases have reported 142K barrels of oil and 300K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
Operator of record
