Irvin East #770H (API 42-283-36395) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed October 30, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 10, 2018, 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 Carrizo, Wilcox, Escondido, Olmos.

Its lease has reported 8.07M barrels of oil and 8.11M mcf of gas since October 2011, last reporting in July 2026. The lease carries 36 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.
