Chalk G. O. -D- #24 (API 42-227-34192) is a well in Howard County operated by Citation Oil & Gas Corp., completed November 30, 2009 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 16, 1987, permitted to 6,375 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 Clear Fork, Tubb, Wichita-Albany.

Its 2 leases have reported 1.27M barrels of oil and 259K mcf of gas since January 1993, last reporting in July 2026. The leases carry 37 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.
