Sarah S #1635 (API 42-003-43567) is a well in Andrews County operated by Cog Operating LLC, completed March 25, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 28, 2011, permitted to 11,600 ft.
It was permitted by Pdc Energy and has since transferred to Cog Operating LLC on the wellbore schedule.

Its lease has reported 384K barrels of oil and 649K mcf of gas since June 2010, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
