Scarborough #4 (API 42-003-07857) is a well in Andrews County operated by Unitex Oil & Gas L.L.C., completed June 16, 1945 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 16, 1979, permitted to 7,412 ft.
It was permitted by Union Oil Company Of California and has since transferred to Unitex Oil & Gas L.L.C. on the wellbore schedule.
Its lease has reported 944K barrels of oil and 92K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
