Pierson William Estate #11 (API 42-165-02472) is a well in Gaines County operated by Hilcorp Energy Company, completed August 17, 2009 and listed as shut in on the RRC schedule, shut in December 1, 2008.

The RRC has issued one drilling permit, issued May 27, 2009, permitted to 11,045 ft.

It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 8 formation tops, including San Andres, Glorieta, Clear Fork, Cisco.

Its 3 leases have reported 1.15M barrels of oil and 1.13M mcf of gas since January 1993, last reporting in July 2026. The leases carry 20 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
