La Salle County · Briscoe Ranch (Eagleford) field · Producing · Horizontal
Briscoe Cochina East Ranch #45H (API 42-283-34158) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed July 28, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 13, 2013, permitted to 8,238 ft.
It was permitted by Anadarko E&P Onshore LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its 2 leases have reported 18.3M barrels of oil and 63.1M mcf of gas since May 2010, last reporting volume in April 2026. The leases carry 123 wells, so these are lease totals, not this well alone.
