Sampson Heirs #6 (API 42-473-30485) is a plugged well in Waller County, plugged July 19, 2011, last operated by Nupower Energy LLC.
The RRC has issued 3 drilling permits (amended once) between 1999 and 2003, permitted to 2,400 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 2 leases have reported 745K barrels of oil and 19.5K mcf of gas since May 1999, last reporting in July 2026. The leases carry 13 wells, so these are lease totals, not this well alone.
