Arnold D Unit #55H (API 42-283-34602) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed August 30, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued February 28, 2014, permitted to 8,096 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 12 formation tops, including Carrizo, Wilcox, Escondido, Olmos.

Its 2 leases have reported 526K barrels of oil and 1.18M mcf of gas since October 2012, last reporting in July 2026. The leases carry 6 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.
