Alfonso #16 (API 42-505-34245) is a well in Zapata County operated by Hilcorp Energy Company, completed January 26, 2001 and listed as swr-10-well on the RRC schedule, shut in November 1, 2007.
The RRC has issued one drilling permit, issued November 15, 2000, permitted to 10,320 ft.
It was permitted by Houston Exploration Company, The and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 101 barrels of oil and 268K mcf of gas since December 2000, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
