McMullan R. B. A #1
Crockett County · Davidson Ranch (Penn. 7890) field · Producing · Vertical
Mcmullan R. B. A #1 (API 42-105-33161) is a well in Crockett County operated by R2q Operating LLC, completed July 17, 1998 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1980 and 1998, permitted to 9,170 ft.
It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Pennsylvanian.
Its 2 leases have reported 12 barrels of oil and 626K mcf of gas since January 1993, last reporting volume in March 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
