Williams Unit #1 (API 42-167-31510) is a well in Galveston County operated by Frio Operations Inc., completed February 16, 2017.
The RRC has issued one drilling permit, issued November 30, 2012, permitted to 10,000 ft.
It was permitted by Houston Petroleum Company and has since transferred to Frio Operations Inc. on the wellbore schedule.
Completion filings report 11 formation tops, including Marg, F20, F24, F30.
Its 3 leases have reported 48.6K barrels of oil and 189K mcf of gas since January 2013, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
