Reservoir Studies With Geostatistics To Forecast Performance

Abstract

Summary Example geostatistics and streamtube applications are presented for waterflood and CO2 flood in two low-permeability sandstone reservoirs. The hybrid approach of combining fine vertical resolution in cross-sectional models with streamtubes resulted in models that showed water channeling and provided realistic performance estimates. Results indicate that the combination of detailed geostatistical cross sections and fine-grid streamtube models offers a systematic approach for realistic performance forecasts.
