Viscosity is a vital parameter in petroleum engineering calculations. Its measurement is sometimes time consuming and not reliable especially in gas injection process. In this project by using PVT cell, pulse viscometer and ECLIPSE TM software viscosity of crude oil will be determined during co 2 swelling test. Therefore at the end of project viscosity change by co2 content of crude oil will be provided for using in other projects.
