Owen-Chalk #46

Howard County · Howard Glasscock (Consolidated) field · Injection · Vertical

Owen-Chalk #46 (API 42-227-34081) is a well in Howard County operated by Citation Oil & Gas Corp., completed July 16, 2015 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued October 31, 1986, permitted to 2,500 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 5 formation tops, including Yates, Seven Rivers, Queen, Grayburg.

Its 2 leases have reported 758K barrels of oil and 229K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 57 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 257K barrels injected in the 12 months reported through December 2025.
