Owen-Chalk #48 (API 42-227-34087) is a well in Howard County operated by Citation Oil & Gas Corp., completed September 8, 1988.

The RRC has issued one drilling permit, issued November 12, 1986, permitted to 2,600 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 in July 2026. The leases carry 57 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.
