Mitchell County · Iatan East Howard field · Shut In · Vertical
Foster W. L. #1 #4 B (API 42-335-31920) is a well in Mitchell County operated by Bce-Mach Iii LLC, completed May 20, 1981 and listed as shut in on the RRC schedule, shut in September 1, 2001.
The RRC has issued one drilling permit, issued February 24, 1981, permitted to 2,978 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.
Its lease has reported 1.94M barrels of oil and 144K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 99 wells, so these are lease totals, not this well alone.
