South Cowden Ellenburger Unit #2
Ector County · Cowden South (Ellenburger) field · Vertical
South Cowden Ellenburger Unit #2 (API 42-135-04674) is a well in Ector County operated by Oxy USA Inc., completed March 15, 1955.
The RRC has issued 2 drilling permits (amended once) between 1995 and 2017, permitted to 11,800 ft.
It was permitted by Oxy USA Wtp LP and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Grayburg, Canyon, Wolfcamp, Devonian.
Its 3 leases have reported 483K barrels of oil and 1.49M mcf of gas since January 1993, last reporting in July 2026. The leases carry 13 wells, so these are lease totals, not this well alone.
