Sterling County · Conger (Penn) field · Producing · Vertical
Grigsby Mattie #8 (API 42-431-33153) is a well in Sterling County operated by Burk Royalty CO. Ltd., completed October 23, 2005 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 27, 2005, permitted to 8,430 ft.
It was permitted by Range Production Company and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 6 formation tops, including T/San Andres, T/Glorietta, T/Clearfork, B/Wolfcamp.
Its lease has reported 76.1K barrels of oil and 4.22M mcf of gas since January 1993, last reporting in July 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
