Pinchback Seawillow Mrs. #16
Jefferson County · Amelia (Frio 6) field · Vertical
Pinchback Seawillow Mrs. #16 (API 42-245-31503) is a well in Jefferson County operated by Tri City Oil CO. LLC, completed November 14, 1986.
The RRC has issued one drilling permit, issued July 3, 1981, permitted to 7,300 ft.
It was permitted by Exxon Corp. and has since transferred to Tri City Oil CO. LLC on the wellbore schedule.
Its 2 leases have reported 51.2K barrels of oil and 999 mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Exxon Corp.; the EWA schedule now lists a different operator.
