Maverick County · Briscoe Ranch (Eagleford) field  · Horizontal

Glass A #4501H (API 42-323-33363) is a plugged horizontal well in Maverick County, plugged March 26, 2022, last operated by Endeavor Natural Gas LP.

The RRC has issued one drilling permit, issued August 17, 2010, permitted to 6,000 ft.

It was permitted by Newfield Exploration Company and has since transferred to Endeavor Natural Gas LP on the wellbore schedule.

Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its 2 leases have reported 7.95K barrels of oil and 235K mcf of gas since September 2010, last reporting in March 2022. The leases carry 3 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
