Carla South Spur Unit A #1H (API 42-127-36476) is a horizontal well in Dimmit County operated by SN EF Maverick LLC, completed January 8, 2015.
The RRC has issued one drilling permit, issued July 28, 2014, permitted to 7,300 ft.
It was permitted by Anadarko E&P Onshore LLC and has since transferred to SN EF Maverick LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Midway, Escondido, Olmos, San Miguel.
Its 2 leases have reported 471K barrels of oil and 1.92M mcf of gas since January 2015, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
