Sieber #2
Yoakum County · Bronco E. (Wolfcamp) field · Vertical
Sieber #2 (API 42-501-31140) is a well in Yoakum County operated by Burk Royalty CO. Ltd., completed March 28, 2007.
The RRC has issued 2 drilling permits between 2006 and 2016, permitted to 12,400 ft.
It was permitted by Custer & Wright Operating, Inc. and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, San Andres, Devonian.
Its 2 leases have reported 97.1K barrels of oil and 55.3K mcf of gas since March 2005, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 3.2M barrels injected in the 12 months reported through November 2025.
