Lasiter-Wood ET AL Unit #1 (API 42-507-32460) is a horizontal well in Zavala County operated by Flint Oak Energy LLC, completed November 6, 2008 and listed as producing on the RRC schedule, shut in March 1, 2009.
The RRC has issued one drilling permit, issued August 4, 1992, permitted to 9,330 ft.
It was permitted by Oryx Energy Company and has since transferred to Flint Oak Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including 1st Lime, Anacacho, Austin Chalk.
Its 2 leases have reported 413K barrels of oil and 246K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
