Dimmit County · Briscoe Ranch (Eagleford) field · Producing · Horizontal
South Spur Unit B #1H (API 42-127-36676) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed January 30, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 26, 2014, permitted to 6,896 ft.
It was permitted by Anadarko E&P Onshore LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Midway, Escondido, Olmos, San Miguel.
Its 2 leases have reported 760K barrels of oil and 3.38M mcf of gas since January 2015, last reporting volume in April 2026. The leases carry 11 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Jan 10, 2018. Gamma ray. 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.
