Chalk -A- #10 (API 42-227-34189) is a well in Howard County operated by Excel Energy CO., completed September 11, 1987.
The RRC has issued one drilling permit, issued August 24, 1987, permitted to 2,600 ft.
It was permitted by Calley, Bob and has since transferred to Excel Energy CO. on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its 2 leases have reported 149K barrels of oil and 152 mcf of gas since January 1993, last reporting in July 2026. The leases carry 12 wells, so these are lease totals, not this well alone.
