Dimmit County · Briscoe Ranch (Eagleford) field · Producing · Horizontal
Diamond H Ranch #20H (API 42-127-36482) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed March 17, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 25, 2014, permitted to 7,518 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 11 formation tops, including Midway, Escondido, Olmos, San Miguel.
Its 3 leases have reported 7.32M barrels of oil and 16.2M mcf of gas since June 2010, last reporting volume in April 2026. The leases carry 47 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, 2 of them with a digital LAS file, the latest received Mar 26, 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.
