Uno Mas -A- #1
LA Salle County · Strickhausen (Olmos Tri-Bar) field · Vertical
Uno Mas -A- #1 (API 42-283-31052) is a well in La Salle County operated by Virtex Operating Company Inc., completed April 3, 1984.
The RRC has issued one drilling permit, issued January 6, 1984, permitted to 8,700 ft.
It was permitted by Sun Expl. & Prod. CO.-Corpus and has since transferred to Virtex Operating Company Inc. on the wellbore schedule.
Completion filings report one formation top, including Olmos.
Its 2 leases have reported 2.83K barrels of oil and 427K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
