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.

2. X-ax is – calcu lated value, Y-axis – histor ical value
3 . Green b isec to r l ine – calculated value of p arameter is equal to h istor ical for the wel ls on th is l ine
4. To lerance – Red l ines – 10% deviat ion from the bisector (for w el l deviat ion between calculated
and his torical value is val id)
Calculated and historical oil total for wells
don’t match (residual in more than 10%)
Red wells in the table and graph
Calculated oil rate is equal to historical oil
rate at this time step (between red lines)
Green wells in the table and graph.
