Dimmit County · Briscoe Ranch (Eagleford) field · Producing · Horizontal
Lehmann Unit B Dim #1H (API 42-127-34914) is a horizontal well in Dimmit County operated by Ineos USA Oil & Gas LLC, completed April 7, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 25, 2012, permitted to 7,438 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 563K barrels of oil and 1.27M mcf of gas since November 2012, last reporting volume in April 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
