Howard County · Howard Glasscock (Consolidated) field  · Vertical

Chalk G. O. #25 W (API 42-227-33069) is a plugged well in Howard County, plugged November 7, 2019, last operated by Citation Oil & Gas Corp..

The RRC has issued one drilling permit, issued May 6, 1983, permitted to 3,200 ft.

It was permitted by Conoco Inc. and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.

Completion filings report 3 formation tops, including Grayburg, San Andres, Glorieta.

Its 3 leases have reported 350K barrels of oil and 84.5K mcf of gas since January 1993, last reporting in July 2026. The leases carry 30 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.
