Vela Lazaro #1 (API 42-131-37094) is a well in Duval County operated by Welderxp Ltd., completed July 20, 2001 and listed as temp abandoned on the RRC schedule, shut in January 1, 2016.

The RRC has issued 2 drilling permits between 1988 and 1990, permitted to 7,860 ft.

It was permitted by Samedan Oil Corporation and has since transferred to Welderxp Ltd. on the wellbore schedule.

Completion filings report 3 formation tops, including Frio, Jackson, Hockley.

Its 2 leases have reported 59.7K barrels of oil and 2.96M mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 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.
