Blocker -B- #4 (API 42-317-36708) is a well in Martin County operated by Xto Energy Inc., completed June 25, 2012 and listed as shut in on the RRC schedule, shut in October 1, 2025.

The RRC has issued one drilling permit, issued April 6, 2011, permitted to 10,995 ft.

It was permitted by Berry Oil Comp. and has since transferred to Xto Energy Inc. on the wellbore schedule.

Completion filings report 6 formation tops, including Yates, San Andres, Clear Fork, Spraberry.

Its lease has reported 155K barrels of oil and 255K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
