Alexander Unit 66 #1H (API 42-211-35183) is a horizontal well in Hemphill County operated by Presidio Petroleum LLC, completed August 11, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 3, 2013, permitted to 9,200 ft.
It was permitted by Apache Corporation and has since transferred to Presidio Petroleum LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Cottage Grove, Checkerboard, Cleveland.
Its lease has reported 143K barrels of oil and 836K mcf of gas since August 2013, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
