Duval County · Jaboncillos (Hockley 5900) field · Vertical
Vela Lazaro #2 (API 42-131-37121) is a well in Duval County operated by Welderxp Ltd., completed July 13, 1988.
The RRC has issued 2 drilling permits in 1988, permitted to 8,000 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 57.9K barrels of oil and 491K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
