WELL · 42-135-04993 · DISTRICT 8
Ratliff #1
Ector County · Ratliff (Penn.) field · Vertical
Ratliff #1 (API 42-135-04993) is a well in Ector County operated by Antelope Production CO., completed August 25, 1983.
The RRC has issued 4 drilling permits between 1978 and 1993, permitted to 12,400 ft.
It was permitted by Amoco Production Company and has since transferred to Antelope Production CO. on the wellbore schedule.
Its 2 leases have reported 43.3K barrels of oil and 389K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
