Crane County · Sand Hills (McKnight) field · NO Production · Vertical
Mcknight M. B. -B- #4 (API 42-103-32721) is a well in Crane County operated by Heifer Production Company LLC, completed December 1, 1981 and listed as no production on the RRC schedule, shut in December 1, 2024.
The RRC has issued one drilling permit, issued October 14, 1981, permitted to 3,458 ft.
It was permitted by Alps Oil Company and has since transferred to Heifer Production Company LLC on the wellbore schedule.
Its lease has reported 134K barrels of oil and 336K mcf of gas since January 1993, last reporting volume in November 2024. The lease carries 10 wells, so these are lease totals, not this well alone.
