Winans Living Trust B #1
Atascosa County · Somerset field · Vertical
Winans Living Trust B #1 (API 42-013-31452) is a well in Atascosa County operated by Southwest Loop 1604 Ltd., completed May 24, 1982.
The RRC has issued one drilling permit, issued April 8, 1982, permitted to 1,600 ft.
It was permitted by Flori-Tex Energy Corp. and has since transferred to Southwest Loop 1604 Ltd. on the wellbore schedule.
Its 2 leases have reported 4.47K barrels of oil and 90 mcf of gas since January 1993, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
Operator of record
