L. Foster -8- #6 (API 42-431-32166) is a well in Sterling County operated by Burk Royalty CO. Ltd., completed January 25, 1991 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 29, 1990, permitted to 8,275 ft.
It was permitted by American Cometra, Inc. and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Wolfcamp, Cisco, Canyon.
Its lease has reported 42.9K barrels of oil and 1.67M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
