Midland County · Spraberry (Trend Area) field · Producing · Vertical
Branch 102 #4 (API 42-329-39568) is a well in Midland County operated by Diamondback E&P LLC, completed January 6, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 17, 2014, permitted to 11,400 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 9 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 292K barrels of oil and 1.09M mcf of gas since February 2005, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
1 log loaded from the RRC's log index, the latest received Dec 14, 2017. 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.
