Mcfarlane J.W. #4D (API 42-059-36235) is a well in Callahan County operated by Cwo Energy LLC, completed September 22, 1992 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued April 17, 1992, permitted to 1,800 ft.
It was permitted by Sequoia Fossil Fuels, Inc. and has since transferred to Cwo Energy LLC on the wellbore schedule.

Its lease has reported 4.04K barrels of oil and 21 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.
