Dimmit County · Briscoe Ranch (Eagleford) field · Shut IN  · Horizontal

Big Wells South Dim #F 2H (API 42-127-37299) is a horizontal well in Dimmit County operated by Ineos USA Oil & Gas LLC, completed January 24, 2017 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued May 10, 2016, permitted to 9,000 ft.

It was permitted by Chesapeake Operating, L.L.C. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Escondido, San Miguel, Olmos, Anacacho.

Its lease has reported 3.79M barrels of oil and 7.07M mcf of gas since September 2011, last reporting in July 2026. The lease carries 19 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.
