Davis T. W. #230 (API 42-157-31510) is a plugged well in Fort Bend County, plugged June 29, 2021, last operated by Hamman Oil & Refining Company.
The RRC has issued one drilling permit, issued January 6, 1984, permitted to 4,000 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Hamman Oil & Refining Company on the wellbore schedule.
Completion filings report 2 formation tops, including Miocene (undifferentiated), Frio.
Its lease has reported 1.14M barrels of oil and 284K mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 96 wells, so these are lease totals, not this well alone.
