Wight Unit #159 (API 42-135-36601) is a well in Ector County operated by United Oil & Shale LLC, completed August 3, 1993 and listed as shut in on the RRC schedule, shut in December 1, 2020.

The RRC has issued one drilling permit (amended once), issued February 12, 1992, permitted to 4,500 ft.

It was permitted by Conoco Inc. and has since transferred to United Oil & Shale LLC on the wellbore schedule.

Completion filings report one formation top, including Grayburg.

Its lease has reported 1.15M barrels of oil and 1.44M mcf of gas since January 1993, last reporting in July 2026. The lease carries 159 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.
