Chalk G. O. -D- #17 (API 42-227-30270) is a well in Howard County operated by Citation Oil & Gas Corp., completed May 18, 2012 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued May 4, 1983, permitted to 3,920 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 Grayburg, San Andres, Glorieta, Clear Fork.
Its 2 leases have reported 1.27M barrels of oil and 259K mcf of gas since January 1993, last reporting in July 2026. The leases carry 37 wells, so these are lease totals, not this well alone.
