Lynch Estate 10 #4 (API 42-329-36565) is a well in Midland County operated by Diamondback E&P LLC, completed June 13, 2010 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued March 12, 2010, permitted to 11,500 ft.

It was permitted by Cog Operating LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 5 formation tops, including T. Spraberry, T. Dean, T. Wolfcamp, T. Strawn.

Its lease has reported 237K barrels of oil and 985K mcf of gas since December 2007, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
