Chalk G. O. -D- #13 (API 42-227-34322) is a well in Howard County operated by Citation Oil & Gas Corp., completed May 13, 2014 and listed as shut in on the RRC schedule, shut in October 1, 2024.

The RRC has issued one drilling permit, issued May 2, 1988, permitted to 3,300 ft.

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

Completion filings report 7 formation tops, including Yates, Seven Rivers, Queen, Grayburg.

Its 3 leases have reported 2.04M barrels of oil and 442K mcf of gas since January 1993, last reporting in July 2026. The leases carry 64 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

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