Vela Serapio Heirs B #23 (API 42-505-33881) is a well in Zapata County operated by Hilcorp Energy Company, completed January 21, 2001 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended 3 times), issued December 7, 1998, permitted to 9,137 ft.
It was permitted by Conoco Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 5 formation tops, including 7483 Sand, 7650 B Sand, 7550 B Sand, 8150 Sand.
Its 2 leases have reported 19.5K barrels of oil and 4.91M mcf of gas since December 2000, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
