Brownlee William T. #4 (API 42-295-31341) is a well in Lipscomb County operated by Bce-Mach II LLC, completed August 12, 1983 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 21, 1983, permitted to 7,600 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Bce-Mach II LLC on the wellbore schedule.
Its lease has reported 21.6K barrels of oil and 397K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
