Chambers County · Trinity Bay (Frio 5 East) field · Vertical
Trinity Bay State Unit NO. 1 #87 (API 42-071-03190) is a well in Chambers County operated by Galveston Bay Operating CO LLC, completed November 1, 1964.
The RRC has issued 5 drilling permits between 1980 and 1985, permitted to 8,552 ft.
It was permitted by Exxon Corp. and has since transferred to Galveston Bay Operating CO LLC on the wellbore schedule.
Completion filings report one formation top, including Frio.
Its 3 leases have reported 1.5K barrels of oil and 108 mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
