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.
