Cmww Unit A Dim #3H (API 42-127-38097) is a horizontal well in Dimmit County operated by Ineos USA Oil & Gas LLC, completed September 21, 2019.

The RRC has issued one drilling permit, issued February 21, 2019, 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, Olmos, San Miguel, Anacacho.

Its 2 leases have reported 258K barrels of oil and 1.96M mcf of gas since March 2013, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
