文摘

Geothermal reservoir models require continuous rock thermal conductivity value. Thermal conductivity interpolation is supported using seismic velocity. Thermal conductivity data are evaluated using variogram analysis. Ordinary kriging and kriging with an external drift are applied. The application is suitable for all kinds of geothermal reservoirs.
