Currently, reservoir characterization is important method in oil industry. The characterization can be generated based on geological condition by using geostatistic appproach. KS field which is the biggest oil field in PT. XYZ Indonesia has applied reservoir characterization.<p>Geological information is an important aspect in a successful reservoir characterization process. Geoscientists have used variogram as a part of geostatistic method extensively to calculate the spatial relationship of various attributes, e.g., volume shale, porosity, and permeability. Proper variogram modeling is a key factor to obtain a geologically-sound reservoir characterization model.<p>This paper discusses how to incorporate geological knowledge as the soft information to improve variogram model in modeling reservoir characterization and how to combine geological knowledge as qualitative data with variogram as quantitative data.
