Lasater M.L. #8 (API 42-507-32416) is a plugged horizontal well in Zavala County, plugged January 20, 2000, last operated by Bluestar Energy Inc..
The RRC has issued one drilling permit, issued May 30, 1991, permitted to 10,650 ft.
It was permitted by Oryx Energy Company and has since transferred to Bluestar Energy Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Midway, San Miguel, Anacacho, Austin Chalk.
Its lease has reported 200K barrels of oil and 613K mcf of gas since January 1993, last reporting in October 2000. The lease carries 10 wells, so these are lease totals, not this well alone.
