Thelma Nelson #4H (API 42-501-36769) is a horizontal well in Yoakum County operated by Burk Royalty CO. Ltd., completed August 2, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 3, 2017, permitted to 5,500 ft.
It was permitted by Walsh Petroleum, Inc. and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, San Andres, Clear Fork.
Its lease has reported 450K barrels of oil and 958K mcf of gas since August 2017, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
