Hemphill County · Mendota NW. (Granite Wash) field · Temp Abandoned · Vertical
Mendota Ranch 51c #4 (API 42-211-33686) is a well in Hemphill County operated by Mmgl Txph LLC, completed April 20, 2007 and listed as temp abandoned on the RRC schedule, shut in May 1, 2015.
The RRC has issued one drilling permit (amended once), issued August 23, 2006, permitted to 11,450 ft.
It was permitted by Dominion Oklahoma Texas E&P, Inc and has since transferred to Mmgl Txph LLC on the wellbore schedule.
Completion filings report 7 formation tops, including T/Brn Dolomite, T/Brown Dolomite, B/Heebner Douglas, Cleveland.
Its 3 leases have reported 8.69K barrels of oil and 314K mcf of gas since November 2006, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
