Abstract

Field X which is being developed is still in the exploration stage which in its progress has drilled 5 exploration wells (A, B, C, D and E) from 6 planned wells. The purpose of this study is to remodel using data from the five wells, with the aim of obtaining the latest geothermal system model and estimation of its energy potential. The method used in this modelling with simulations using the 3D leapfrog software so that will be easier to give a description of geometric shapes and heat sources. While in the estimation of energy potential the volumetric method is used with reference to SNI 13-6482-2000. The results of this modelling simulation were obtained clearly at a depth of -1750m with visible geometric shapes from field geothermal X. From the analysis of temperature ramps obtained a medium temperature geothermal system (125oC -225oC). Estimation of the for energy that can be generated for electricity (MWe) using montecarlo simulator, will produce P10, P50 and P90.
