Shelley #1 (API 42-135-39160) is a well in Ector County operated by Diamondback E&P LLC, completed December 20, 2006 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 27, 2006, permitted to 11,000 ft.
It was permitted by Cambrian Management Ltd and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Dean, Wolfcamp, Lwr Wolfcamp.
Its lease has reported 184K barrels of oil and 559K mcf of gas since December 2006, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
