Glasscock County · Spraberry (Trend Area) field · Vertical
Butler #1 (API 42-173-31103) is a well in Glasscock County operated by Oxyrock Operating LLC, completed March 30, 1981.
The RRC has issued 2 drilling permits between 1980 and 2003, permitted to 8,600 ft.
It was permitted by Arkland Producing CO., Inc. and has since transferred to Oxyrock Operating LLC on the wellbore schedule.
Its 2 leases have reported 107K barrels of oil and 280K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
