Raul Volpe Heirs #1
Zapata County · Haynes (Middle Wilcox Cons.) field · SWR-10-Well · Vertical
Raul Volpe Heirs #1 (API 42-505-35948) is a well in Zapata County operated by Hilcorp Energy Company, completed January 25, 2008 and listed as swr-10-well on the RRC schedule, shut in January 1, 2017.
The RRC has issued one drilling permit (amended once), issued August 8, 2007, permitted to 11,807 ft.
It was permitted by Conocophillips Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 3 barrels of oil and 737K mcf of gas since December 2007, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
