Sawyer 46 #2 (API 42-317-34453) is a well in Martin County operated by Diamondback E&P LLC, completed July 8, 2004 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended once) between 2004 and 2018, permitted to 12,000 ft.

It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Spraberry, Wolfcamp, U. Wolfcamp, L. Wolfcamp.

Its lease has reported 114K barrels of oil and 249K mcf of gas since February 2004, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
