Williams Unit #8
Montgomery County · Lake Creek (Wilcox Consolidated) field · Vertical
Williams Unit #8 (API 42-339-30788) is a well in Montgomery County operated by Daylight Petroleum LLC, completed February 26, 1988.
The RRC has issued 2 drilling permits between 1987 and 2019, permitted to 12,300 ft.
It was permitted by Sydri Operating, LLC and has since transferred to Daylight Petroleum LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Yegua, Cockfield, Wilcox.
Its 2 leases have reported 9 barrels of oil and 727K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
