Hardin-Rayes Unit #18H (API 42-311-37234) is a horizontal well in Mcmullen County operated by Javelin Energy Partners Mgmt LLC, completed September 7, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 4, 2022, permitted to 11,000 ft.

It was permitted by Callon (Eagle Ford) LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Wilcox, Escondido, Olmos, Anacacho.

Its lease has reported 1.41M barrels of oil and 1M mcf of gas since June 2011, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
