Chaparrosa A #2H (API 42-507-32740) is a horizontal well in Zavala County operated by Arrco Operating LLC, completed October 10, 2010 and listed as no production on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 2009 and 2011, permitted to 6,000 ft.
It was permitted by Espada Operating LLC and has since transferred to Arrco Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Anacho, Frio, Austin Chalk, Eagle Ford.
Its 2 leases have reported 3.39K barrels of oil since July 2009, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
