Abstract

The potential resources and reserves of a geothermal field can be described by several reservoir parameters such as temperature, pressure, and entalpy represent the heat energy contained in the fluid reservoir. One very important thing to present a geothermal system is a thermal distribution. In the research do forward modeling of distribution thermal condution geothermal system from top reservoir to the surface. This research aims to model the distribution of the termal conduction 2D from surface by comparing temperature the known value and compare the change in the temperature distribution of each layer with a real model of the geothermal reservoir. The conductivity thermal’s measurement had been conducted at 100 cm depth on Ulu Belu’s area which is used needle probe. Measurment of Conductivity Thermal (CT) done simultant with magnetic acquisition at student event "GEOWES UNILA 2017". Magnetic methode is used in confirming result from CT methode. The transient heating of needle probe is used to measure the thermal conductivity and shallow depth temperature. The temperatures that have been measured are 17.42-52.93 0C and the highest value of heat flow that have been measured is 2.1 W/mK. Temperature measurements at shallow depths contain useful information about features of the geological structures in Ulu Belu area. Essentials similarity between thermal and magnetic prospecting make it possible to apply to thermal prospecting modification of the rapid method characteristic point developed for magnetic prospecting. The interpretation result is the upper edge location of anomaly at 12.13 m below the surface.
