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

The RRC has issued one drilling permit (amended once), issued April 29, 2008, permitted to 10,148 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Dean, Wolcamp, Wolfcamp.
Its lease has reported 57.2K barrels of oil and 60.1K mcf of gas since October 2008, with no volume in the three years through August 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Click a log to get its files from the RRC (free account). It opens in a new tab on the RRC's log search for this well, which lists each file to view or download; the RRC has no address for a single file.

"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.
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.
