Chalk G. O. -C- #24 (API 42-227-32183) is a well in Howard County operated by Citation Oil & Gas Corp., completed July 14, 1980 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued June 2, 1980, permitted to 3,250 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 2 leases have reported 1.3M barrels of oil and 140K mcf of gas since January 1993, last reporting in July 2026. The leases carry 39 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 246K 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.
