Pierce Estates #C258 (API 42-481-35173) is a well in Wharton County operated by Remora Management LLC, completed November 15, 2011 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued February 8, 2011, permitted to 7,500 ft.
It was permitted by Apache Corporation and has since transferred to Remora Management LLC on the wellbore schedule.

Its lease has reported 4.66M barrels of oil and 4.21M mcf of gas since January 1993, last reporting in July 2026. The lease carries 146 wells, so these are lease totals, not this well alone.
