San Patricio County · Portilla (8500 Sand) field · Vertical
Welder M. S. #83 (API 42-409-32469) is a well in San Patricio County operated by Abraxas Petroleum Corporation, completed June 9, 1995.
The RRC has issued 2 drilling permits (amended once) in 1995, permitted to 9,000 ft.
It was permitted by Abraxas Production Corporation and has since transferred to Abraxas Petroleum Corporation on the wellbore schedule.
Completion filings report 6 formation tops, including Portilla (7400 Sand), Portilla (7400 Sd.), Portilla (8100 Sand), 8100 Sand.
Its 4 leases have reported 3.39M barrels of oil and 7.7M mcf of gas since January 1993, last reporting in July 2026. The leases carry 167 wells, so these are lease totals, not this well alone.
