Plugged

Howard County · Howard-Glasscock (Glorieta) field · Vertical

Clay H. R. #43 (API 42-227-33259) is a plugged well in Howard County, plugged July 1, 2016, last operated by Endeavor Energy Resources L.P..

The RRC has issued 2 drilling permits between 1983 and 1988, permitted to 3,600 ft.

It was permitted by Exxon Corp. and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.

Completion filings report 3 formation tops, including Seven Rivers, Glorieta, Clear Fork.

Its 2 leases have reported 135K barrels of oil since January 1993, last reporting volume in April 2026. The leases carry 55 wells, so these are lease totals, not this well alone.
