Chalk Sloan #22
Howard County · Howard-Glasscock (Glorieta) field · Vertical
Chalk Sloan #22 (API 42-227-33894) is a well in Howard County operated by Conocophillips Company, completed March 9, 2010.
The RRC has issued one drilling permit, issued October 30, 1985, permitted to 3,400 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 6 formation tops, including Yates, Seven Rivers, Queen, San Andres.
Its 2 leases have reported 465K barrels of oil and 136K mcf of gas since January 1993, last reporting in July 2026. The leases carry 27 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 128K barrels injected in the 12 months reported through December 2025.
