WELL · 42-475-35458 · DISTRICT 8
Winter #1
Ward County · Marston Ranch (Clearfork) field · Producing · Vertical
Winter #1 (API 42-475-35458) is a well in Ward County operated by N & B Oil And Gas LLC, completed December 1, 2010 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 2008 and 2011, permitted to 9,500 ft.
It was permitted by Northstar Operating Company and has since transferred to N & B Oil And Gas LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Clear Fork, Silurian (undifferentiated), Devonian, Connell.
Its 2 leases have reported 300K barrels of oil and 841K mcf of gas since April 2009, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
