Atascosa County · Fashing (Edwards Lime -A-) field · Producing · Vertical
Tom A GU 4 #3 (API 42-013-33179) is a well in Atascosa County operated by Capital Star Oil & Gas Inc., completed March 22, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 23, 1985, permitted to 10,900 ft.
It was permitted by Enserch Exploration, Inc and has since transferred to Capital Star Oil & Gas Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Austin Chalk, Edwards.
Its 2 leases have reported 3.19K barrels of oil and 4.85M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
