Heat Flow Measurement In Dhamar Prospective Geothermal Field, Yemen

Abstract

This research presents the thermal gradient and heat flow in the Dhamar Quaternary Volcanic Field, where fumaroles, hot springs, as well as hot well waters and domestic wells are distributed, throughout an area exceeding 200km2. Field data from shallow holes temperatures in the Alisis Field are used to interpret conduction, with the aim of estimating the amount of heat being lost naturally. 1291MWt is lost naturally by conductive heat flow from the field of Al-lisi. Results available from the domestic wells indicate that thermal gradient varies from 41 ºC/km to more than 250 ºC/km.
