Lasater W S #1 (API 42-503-41537) is a well in Young County operated by Rover Operating Company LLC, completed June 28, 2008.
The RRC has issued one drilling permit, issued May 19, 2008, permitted to 1,850 ft.
It was permitted by Martin Well Service and has since transferred to Rover Operating Company LLC on the wellbore schedule.
Completion filings report one formation top, including Strawn.
Its 2 leases have reported 4.22K barrels of oil and 29.2K mcf of gas since June 2008, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
