Corrigan Cowden Unit #318R (API 42-135-37585) is a horizontal well in Ector County operated by Oxy USA Inc., completed July 14, 1999 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1997 and 1999, permitted to 4,750 ft.
It was permitted by Arco Permian and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Yates, Grayburg.
Its lease has reported 6.42M barrels of oil and 1.79M mcf of gas since January 1993, last reporting in July 2026. The lease carries 56 wells, so these are lease totals, not this well alone.
