Midland County · Spraberry (Trend Area) field · Shut In · Vertical
ST #4107 (API 42-329-35973) is a well in Midland County operated by Diamondback E&P LLC, completed September 13, 2008 and listed as shut in on the RRC schedule, shut in April 1, 2021.
The RRC has issued one drilling permit (amended once), issued June 23, 2008, permitted to 10,905 ft.
It was permitted by Windsor Energy Group, L.L.C. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report one formation top, including Spraberry.
Its lease has reported 16.1M barrels of oil and 48.4M mcf of gas since September 2008, last reporting volume in August 2026. The lease carries 124 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Aug 1, 2011. 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.
