Preparing a project and loading data
The initialization procedure is largely the same as that used in PTA. The interpretation engineer
inputs PVT data, geometric well and reservoir information, the following table can be used as a
guide:
Type of data

Yes
Pressure history
Old stuff: No
Right stuff: Yes
PVT, correlations, tables or constraints
Yes

Field map with surrounding wells based
on seismic interpretation
Preferably
Production history of surrounding wells
Preferably
Complete completion log preferably with
a permeability log. Core and core
