Mountjoy Helen L. et AL #8
Crosby County · Ridge (Clear Fork) field · Vertical
Mountjoy Helen L. ET AL #8 (API 42-107-30385) is a well in Crosby County operated by Columbus Energy Corp., completed September 29, 1979.
The RRC has issued one drilling permit, issued July 23, 1979, permitted to 4,600 ft.
It was permitted by Consolidated Oil & Gas, Inc. and has since transferred to Columbus Energy Corp. on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Glorieta, Clear Fork.
Its 2 leases have reported 2.4M barrels of oil and 391K mcf of gas since January 1993, last reporting in July 2026. The leases carry 216 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
