Abstract
During a prefeasibility study conducted at the Muara Laboh geothermal prospect, geology, geochemistry, and geophysics (3G) data were acquired to define resource size, concession area boundaries, and to serve as input to a development plan to assess the project cost and project economics. In addition to 3G data, a heat loss survey was conducted to provide undisturbed heat flow of the geothermal system. A conceptual model of Muara Laboh was constructed and a numerical model was built on STARS-CMG constrained by heat loss and data from shallow wells. The model was used to estimate subsurface temperature distribution, to estimate the location and thickness of the outflow tongue, and to assist in defining well pad locations during the exploration stage.
