Integrated Analysis of Surface and Borehole Data to Construct the Stratigraphy Model of Bukit Daun Field, Indonesia

Abstract

We present the results of detail stratigraphic identification of the Bukit Daun geothermal field, Indonesia. This study optimizes the available surface and subsurface data to comprehensively reveal the lithology condition of the field with the regional data that is visualized in the 2D and 3D stratigraphic models. The extensive use of the image log analysis has improved the geologic interpretation's confidence, which combines with terrain imagery analysis and drilling parameters and data such as cutting and core. The metasedimentary deposit that contains fossil enables us to predict the formation age of the reservoir rocks. The well test result also supports the geologic influence in permeability.
