E Jost Oil Unit-B- #15S (API 42-383-38583) is a well in Reagan County operated by Crescent Energy Operating LLC, completed December 1, 2016 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued January 2, 2014, permitted to 11,000 ft.

It was permitted by Laredo Petroleum - Dallas, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Queen, Grayburg, San Andres, Clear Fork.

Its lease has reported 58.5K barrels of oil and 613K mcf of gas since May 2012, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
