Rhodes Cowden Unit #507 (API 42-135-35937) is a plugged well in Ector County, plugged June 9, 2026, last operated by Oxy USA Wtp LP.
The RRC has issued one drilling permit, issued July 28, 1988, permitted to 4,350 ft.
It was permitted by Oxy USA Inc. and has since transferred to Oxy USA Wtp LP on the wellbore schedule.
Completion filings report 3 formation tops, including Tansill, Yates, Grayburg.
Its lease has reported 8.15M barrels of oil and 6.14M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 170 wells, so these are lease totals, not this well alone.
