South Callaghan Ranch #120C (API 42-479-36041) is a well in Webb County operated by Aldine Oil And Gas LP, completed April 10, 1994 and listed as temp abandoned on the RRC schedule, shut in November 1, 2013.

The RRC has issued 2 drilling permits between 1994 and 1995, permitted to 9,210 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Aldine Oil And Gas LP on the wellbore schedule.

Completion filings report 2 formation tops, including Wilcox, Lobo 6.

Its 3 leases have reported 588 barrels of oil and 2.44M mcf of gas since April 1994, with no volume in the three years through April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
