Irvin West #15H (API 42-283-35420) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed October 29, 2015 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 16, 2015, permitted to 8,894 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 lease has reported 12.2M barrels of oil and 15.3M mcf of gas since June 2013, last reporting volume in August 2026. The lease carries 75 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
