Howard County · Howard Glasscock (Consolidated) field · Producing · Vertical
Chalk #27 (API 42-227-31489) is a well in Howard County operated by R2q Operating LLC, completed January 5, 1978 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 15, 1977, permitted to 2,990 ft.
It was permitted by Samedan Oil Corporation and has since transferred to R2q Operating LLC on the wellbore schedule.
Its 2 leases have reported 684K barrels of oil and 37.8K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 62 wells, so these are lease totals, not this well alone.
