Martin County · Spraberry (Trend Area) field · Producing · Vertical
Wilbanks 17 #1 (API 42-317-35315) is a well in Martin County operated by Diamondback E&P LLC, completed September 5, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 21, 2008, permitted to 10,842 ft.
It was permitted by Cobra Oil & Gas Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Clear Fork, B/Clearfork, Spraberry, Dean.
Its 2 leases have reported 393K barrels of oil and 907K mcf of gas since September 2008, last reporting volume in April 2026. The leases carry 15 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Jul 26, 2011. Density, Neutron, 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.
