Peck #4 (API 42-461-38523) is a well in Upton County operated by Diamondback E&P LLC, completed September 19, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 28, 2012, permitted to 11,031 ft.
It was permitted by Jamex, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Wolfcamp, Strawn, Atoka.
Its lease has reported 394K barrels of oil and 700K mcf of gas since October 2011, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
