Diamond H Ranch #4H (API 42-127-33892) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed April 29, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 22, 2011, permitted to 7,474 ft.

It was permitted by Anadarko E&P Company LP and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Escondido, Olmos, Eagle Ford.

Its 3 leases have reported 7.16M barrels of oil and 16.2M mcf of gas since June 2010, last reporting in July 2026. The leases carry 47 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.
