Petrophysics modeling is to analysis logs data distribution in plane, like porosity, Sw, permeability etc. users can use facies constraint or not. GES provide 5 algorithms, including Ordinary Kriging, Sequential Gaussian Simulation, Moving Average, Closest and Assign Value.
Petrophysics modeling can be performed with facies model constraint.

All models in GES can be display in intersection window, and overlay well logs data to section profile to double check model quality.

Steps to perform Petrophysics Modeling in GES:
· Go to Model pane → Click the model grid you want to updating
· Go to Geology & Modeling Scenario → Reservoir Modeling → Block Wells → Finish block well
· Go to Geology & Modeling Scenario → Reservoir Modeling → Petrophysics Modeling → Select data for BW Property Name →select Algorithm for each zone → Model Parameter → Variogram Analysis → Algorithm Parameter → Click OK
