Epley J. C. #3
Martin County · Spraberry (Trend Area) field · NO Production · Vertical
Epley J. C. #3 (API 42-317-38208) is a well in Martin County operated by Diamondback E&P LLC, completed December 17, 2012 and listed as no production on the RRC schedule, shut in February 1, 2025.
The RRC has issued one drilling permit (amended twice), issued October 19, 2012, permitted to 11,776 ft.
It was permitted by JM Cox Resources, L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.
Its lease has reported 95.4K barrels of oil and 128K mcf of gas since January 1993, last reporting volume in February 2024. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
3 logs loaded from the RRC's log index, the latest received Nov 24, 2015. Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
