University BL #6 (API 42-383-33886) is a plugged horizontal well in Reagan County, plugged April 23, 2018, last operated by Apache Corporation.
The RRC has issued 3 drilling permits (amended once) between 1988 and 2006, permitted to 9,300 ft.
It was permitted by Marathon Oil Company and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 6 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.
Its 3 leases have reported 45.1K barrels of oil and 223K mcf of gas since January 1993, last reporting in April 2018. The leases carry 5 wells, so these are lease totals, not this well alone.
