WELL · 42-283-35954 · DISTRICT 1
Jasik #37H
LA Salle County · Eagleville (Eagle Ford-1) field · Horizontal
Jasik #37H (API 42-283-35954) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed March 31, 2018.
The RRC has issued one drilling permit (amended once), issued February 21, 2017, permitted to 11,000 ft.
It was permitted by Carrizo (Eagle Ford) LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Wilcox, Escondido, Olmos, Austin Chalk.
Its 2 leases have reported 3.14M barrels of oil and 7.86M mcf of gas since January 2013, last reporting in July 2026. The leases carry 25 wells, so these are lease totals, not this well alone.
