Chalk G. O. -C- #23 (API 42-227-32184) is a well in Howard County operated by Citation Oil & Gas Corp., completed July 30, 2010 and listed as injection on the RRC schedule.

The RRC has issued 2 drilling permits in 1980, permitted to 3,230 ft.

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

Completion filings report 4 formation tops, including San Andres, Grayburg, Glorieta, Clear Fork.

Its 2 leases have reported 791K barrels of oil and 117K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 41 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 227K barrels injected in the 12 months reported through December 2025.

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