Chalk Sloan #23
Howard County · Howard-Glasscock (Wolfcamp 7400) field · Temp Abandoned · Vertical
Chalk Sloan #23 (API 42-227-33952) is a well in Howard County operated by Citation Oil & Gas Corp., completed December 17, 2018 and listed as temp abandoned on the RRC schedule, shut in August 1, 2021.
The RRC has issued one drilling permit, issued January 7, 1986, permitted to 8,000 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.
Completion filings report 12 formation tops, including Transill, Yates, Seven Rivers, Queen.
Its 2 leases have reported 23.6K barrels of oil and 472K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
