Shannon Estate -B- #55 (API 42-105-34165) is a well in Crockett County operated by Clark Oil CO., completed February 1, 1983 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 12, 1982, permitted to 2,500 ft.

It was permitted by Sun Expl. & Prod. CO.-Midland and has since transferred to Clark Oil CO. on the wellbore schedule.

Its lease has reported 945K barrels of oil and 22 mcf of gas since January 1993, last reporting in July 2026. The lease carries 57 wells, so these are lease totals, not this well alone.
