Initial maps  – depth, porosity, block size along X, Y, Z axis, permeability along X, Y, Z axis, transmissibility multipliers, etc.

Calculated maps  – pressure, saturation of oil, water, gas, ternary saturation diagram, reciprocal of formation volume factor for water, oil, gas, reciprocal of viscosity for water, oil, gas, etc.

Resources  – Oil in place, Mobile Oil in Place, Mass Mobile Oil in Place, Gas in Place, etc.

Regions  – Pvtnum (PVT regions), Satnum (saturation regions), FIPnum (Fluid-in-Place regions), Eqlnum (equilibration regions), etc.

User Cuts and User Maps  – maps and cuts that can be created via User Arithmetics.

3D visualization To rotate map  – hold left mouse button and move the mouse To move map  – hold right mouse button and move the mouse To scale map  – roll mouse wheel Default view  – press left + right mouse click Different models views  – Button Views and presentation params
