Welder Ranch #16
San Patricio County · O Neil (5850) field · Producing · Vertical
Welder Ranch #16 (API 42-409-32334) is a well in San Patricio County operated by Proline Energy Resources Inc, completed September 10, 1993 and listed as producing on the RRC schedule, shut in August 1, 2026.
The RRC has issued one drilling permit (amended once), issued March 8, 1990, permitted to 7,500 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Proline Energy Resources Inc on the wellbore schedule.
Completion filings report 8 formation tops, including O'Neil (3400), O'Neil(3400), O'Neil (4550), O'Neil(4550).
Its 2 leases have reported 5.24K barrels of oil and 965K 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.
