Zella Cromwell Ranch #3H (API 42-283-33891) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed October 12, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued April 16, 2013, permitted to 8,331 ft.

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

Completion filings report 10 formation tops, including Sparta, Queen City, Wilcox, Escondido.

Its lease has reported 1.01M barrels of oil and 1.03M mcf of gas since December 2010, 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.
