Pena-Winfield A Unit #52H (API 42-283-33195) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed June 15, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 1, 2012, permitted to 8,306 ft.

It was permitted by Carrizo Oil & Gas, Inc. and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Carrizo, Austin Chalk, Eagle Ford.

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.
