Sampson Heirs #5
Waller County · Brookshire field · Shut IN · Vertical
Sampson Heirs #5 (API 42-473-30480) is a well in Waller County operated by Nupower Energy LLC, completed March 24, 2000 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued May 20, 1999, permitted to 3,000 ft.
It was permitted by H-M Resource Management, Inc. and has since transferred to Nupower Energy LLC on the wellbore schedule.
Completion filings report one formation top, including Miocene (undifferentiated).
Its lease has reported 745K barrels of oil since May 1999, last reporting in July 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by H-M Resource Management, Inc.; the EWA schedule now lists a different operator.
