Ada Hammond Heirs #1
Zavala County · Hammond (San Miguel NO 4) field · Vertical
Ada Hammond Heirs #1 (API 42-507-32660) is a well in Zavala County operated by Arrco Operating LLC, completed November 12, 2005.
The RRC has issued 2 drilling permits between 2005 and 2018, permitted to 5,000 ft.
It was permitted by Caribbean Energy, L.L.C. and has since transferred to Arrco Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Escondido, Olmos, San Miguel.
Its 2 leases have reported 19K barrels of oil and 16.1K mcf of gas since November 2005, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
