Sterling County · Spraberry (Trend Area) field · Producing · Vertical
Mahaffey P. T. #1 (API 42-431-30979) is a well in Sterling County operated by Burk Royalty CO. Ltd., completed December 18, 2012 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1981 and 2012, permitted to 8,200 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report one formation top, including Wolfcamp.
Its 3 leases have reported 44.4K barrels of oil and 712K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
