Winterbotham B #303 (API 42-235-31999) is a well in Irion County operated by Walter Oil & Gas Corporation, completed January 5, 1983 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 4, 1982, permitted to 6,224 ft.
It was permitted by Tuthill & Barbee and has since transferred to Walter Oil & Gas Corporation on the wellbore schedule.
Its lease has reported 12.9K barrels of oil and 478K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
