Williams E. W. JR. #4 (API 42-169-31601) is a well in Garza County operated by Aviator Energy LLC, completed December 12, 1981 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1979 and 1981, permitted to 3,400 ft.
It was permitted by Wtg Exploration, Inc. and has since transferred to Aviator Energy LLC on the wellbore schedule.
Its lease has reported 155K barrels of oil and 25.1K mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
