Clay H. R.-E- #55 (API 42-227-31571) is a plugged well in Howard County, plugged July 3, 2019, last operated by Landmark IP LLC.
The RRC has issued 2 drilling permits between 1978 and 1993, permitted to 3,200 ft.
It was permitted by Conoco Inc. and has since transferred to Landmark IP LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Grayburg, San Andres, Glorieta.
Its 4 leases have reported 909K barrels of oil and 7.09K mcf of gas since January 1993, last reporting in July 2026. The leases carry 152 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Conoco Inc.; the EWA schedule now lists a different operator.
