Diamond H State #13H (API 42-127-36340) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed December 10, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 27, 2014, permitted to 7,588 ft.

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

Completion filings report 12 formation tops, including Midway, Escondido, Olmos, San Miguel.

Its 3 leases have reported 1.38M barrels of oil and 4.13M mcf of gas since July 2010, last reporting in July 2026. The leases carry 16 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.
