Webb County · Beccero Creek (Lobo Cons.) field · Vertical
South Callaghan Ranch #96 (API 42-479-35630) is a plugged well in Webb County, plugged October 20, 2011, last operated by Rosetta Resources Operating LP.
The RRC has issued 2 drilling permits between 1992 and 1993, permitted to 8,200 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 2 formation tops, including Wilcox, Lobo 6.
Its 2 leases have reported 821K mcf of gas since March 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.
