Cinco Terry A #904 (API 42-105-40356) is a well in Crockett County operated by Zarvona Energy LLC, completed October 16, 2007.
The RRC has issued one drilling permit (amended once), issued July 6, 2007, permitted to 9,000 ft.
It was permitted by Approach Operating LLC and has since transferred to Zarvona Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Base Cretaceous (marker), Dean, Canyon.
Its 3 leases have reported 13.1K barrels of oil and 292K mcf of gas since October 2007, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
