Webb County · Big Cowboy (Lobo 1) field · Directional
Stanford P.H. #4 (API 42-479-34548) is a plugged well in Webb County, plugged February 6, 2009, last operated by Rosetta Resources Operating LP.
The RRC has issued 3 drilling permits between 1987 and 1994, permitted to 10,000 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Rosetta Resources Operating LP on the wellbore schedule.
Completion filings report 3 formation tops, including Queen City, Carrizo, Lobo Uncf..
Its 2 leases have reported 484K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
