Hamilton Ranch C #156H (API 42-127-38050) is a horizontal well in Dimmit County operated by Grit Oil & Gas Management LLC, completed May 31, 2019.

The RRC has issued one drilling permit, issued December 31, 2018, permitted to 4,000 ft.

It was permitted by Endeavor Natural Gas, LP and has since transferred to Grit Oil & Gas Management LLC on the wellbore schedule.

Completion filings report 9 formation tops, including Escondido, Olmos, San Miguel, Austin Chalk.

Its 2 leases have reported 11.1M barrels of oil and 30.7M mcf of gas since August 2013, last reporting in July 2026. The leases carry 84 wells, so these are lease totals, not this well alone.
