Cousin Willard 450 #4H (API 42-501-36518) is a horizontal well in Yoakum County operated by Burk Royalty CO. Ltd., completed February 27, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 16, 2014, permitted to 9,000 ft.
It was permitted by Manzano, LLC and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, San Andres, Clear Fork, Glorieta.
Its lease has reported 901K barrels of oil and 2.54M mcf of gas since February 2015, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
