Chalk G. D. E. #27
Howard County · Howard Glasscock (Clear Fork MI) field · Vertical
Chalk G. D. E. #27 (API 42-227-34262) is a well in Howard County operated by Conocophillips Company, completed April 9, 2010.
The RRC has issued 2 drilling permits between 1988 and 1993, permitted to 6,375 ft.
It was permitted by Conoco Inc. and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 3 formation tops, including Clear Fork, Wcab, Wichita-Albany.
Its 2 leases have reported 380K barrels of oil and 96K 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.
