Chalk G. O.-G- #46 (API 42-227-34094) is a well in Howard County operated by Citation Oil & Gas Corp., completed December 18, 2009 and listed as shut in on the RRC schedule, shut in December 1, 2014.

The RRC has issued 2 drilling permits between 1986 and 1993, 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 5 formation tops, including Yates, Queen, Grayburg, San Andres.

Its 3 leases have reported 1.2M barrels of oil and 280K mcf of gas since January 1993, last reporting in July 2026. The leases carry 80 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.
