Ashley -A- #2 (API 42-317-35588) is a well in Martin County operated by Diamondback E&P LLC, completed August 1, 2009 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 2009 and 2016, permitted to 10,826 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 5 formation tops, including Clearforklime, Spraberry, Dean, Wolfcamp.

Its lease has reported 97.1K barrels of oil and 74.5K mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

2 logs loaded from the RRC's log index, the latest received Aug 6, 2010. Neutron. 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.
