Pena-Winfield A Unit #55H (API 42-283-37046) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed March 21, 2021 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 10, 2020, permitted to 11,000 ft.

It was permitted by Callon (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 695K barrels of oil and 869K mcf of gas since July 2012, last reporting in July 2026. The lease carries 3 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.
