Help: computer simulation for co2 injection wells using vfpi

Hi, I have this project where i need to do simulational modeling of wells for co2 injection.
first i need to make a flow model in injection wells then do the calculations using VFPi (and PVTi as i guess) and finally do the assessment of productivity/performance of these injenctions.
I can create my own data, although the reservoir is theoretically located somewhere on the NCS.
My problem is that i have worked with neither vfpi nor pvti i have only got some basic expierence in using ecplipse 100. So thats why i need your help any advices would be great.

See their manuals. Vfpi is good but obsolete now. VFPi simply creates flow performance curves for producers and injectors. (IPR, OPR) at varying pressures and rates.
PVTi is used to calibrate your fluid (experimental/ PVT) data to EOS for incorporating into simulation model (PVT Section of your data file)
