The purpose of article is to determinate the connate water mobility in heavy oil reservoirs. Innovate relative permeability measurement is developed to identify difference between initial water and irreducible water.  In order to examine effect of oil viscosity on relative permeability curves, two factors are important to investigate , 1) mobility of initial water 2) effect of initial water saturation on oil relative permeability. The experiment result show that the initial water is mobile, and that further modifications are needed in order to measure the exact permeability of initial water.
