Cassle H. O. #46 (API 42-151-30030) is a well in Fisher County operated by Boyd & Mcwilliams Energy Group, completed February 23, 1970.
The RRC has issued one drilling permit, issued June 18, 1987, permitted to 4,475 ft.
It was permitted by Sun Expl. & Prod. CO.-Abilene and has since transferred to Boyd & Mcwilliams Energy Group on the wellbore schedule.
Completion filings report one formation top, including Canyon.
Its lease has reported 181K barrels of oil and 19K mcf of gas since January 1993, last reporting in July 2026. The lease carries 37 wells, so these are lease totals, not this well alone.
