Mcmullan R. B. A #4 (API 42-105-38762) is a well in Crockett County operated by R2q Operating LLC, completed February 21, 2003 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued September 13, 2001, permitted to 9,450 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 2 formation tops, including Pennsylvanian, Strawn.
Its 2 leases have reported 162 barrels of oil and 300K mcf of gas since February 2003, last reporting volume in August 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
