Martin County · Spraberry (Trend Area) field · Shut In  · Horizontal

Wilbanks SN 16-15 04 #501H (API 42-317-39969) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed March 24, 2015 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued October 20, 2014, permitted to 8,065 ft.

It was permitted by Energen Resources Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 11 formation tops, including Santa Rosa, Yates, San Andres, Grayburg.

Its lease has reported 466K barrels of oil and 888K mcf of gas since June 2014, last reporting volume in January 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

1 log loaded from the RRC's log index, the latest received Feb 27, 2018. While drilling (MWD). 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.
