Pena A Unit #55H (API 42-283-36878) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed April 1, 2020 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 23, 2019, permitted to 12,000 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 868K barrels of oil and 1.3M mcf of gas since January 2016, last reporting in July 2026. The lease carries 4 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.
