Briscoe Cochina East Ranch #55H
La Salle County · Briscoe Ranch (Eagleford) field · Producing · Horizontal
Briscoe Cochina East Ranch #55H (API 42-283-34176) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed September 12, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 23, 2013, permitted to 8,345 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 3 formation tops, including Olmos, San Miguel, Eagle Ford.
Its 3 leases have reported 18.5M barrels of oil and 63.6M mcf of gas since May 2010, last reporting volume in April 2026. The leases carry 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 28, 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.
