Uno Mas -A- #7 (API 42-283-31170) is a well in La Salle County operated by Virtex Operating Company Inc., completed November 20, 1985.

The RRC has issued one drilling permit, issued September 9, 1985, permitted to 8,600 ft.

It was permitted by Pacific Southwest Exploration CO and has since transferred to Virtex Operating Company Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Carrizo, Wilcox, Escondido.

Its 2 leases have reported 2.83K barrels of oil and 405K 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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
