Cowden-Oliver #3 (API 42-135-34901) is a well in Ector County operated by Baker Operating Inc., completed April 12, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 13, 1985, permitted to 4,270 ft.
It was permitted by Heck Exploration Company and has since transferred to Baker Operating Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Santa Rosa, Anhydrite, Yates, Grayburg.
Its lease has reported 88K barrels of oil and 60K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
