Martinez Unit B Dim #3H (API 42-127-35913) is a horizontal well in Dimmit County operated by Ineos USA Oil & Gas LLC, completed May 7, 2014 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued November 23, 2013, permitted to 9,000 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 362K barrels of oil and 1.96M mcf of gas since May 2012, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
