Hardberger #4 (API 42-165-36159) is a plugged well in Gaines County, plugged January 3, 2013, last operated by Grace Petroleum Operating LLC.

The RRC has issued one drilling permit, issued June 8, 2004, permitted to 11,500 ft.

It was permitted by Encore Operating, L.P. and has since transferred to Grace Petroleum Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including San Andres, Sand Andrews, Wolfcamp, Strawn.

Its lease has reported 1.66M barrels of oil and 993K mcf of gas since October 1996, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
