Abstract
In this paper, the following reservoir fluid characteristics of the Japanese oil fields are estimated; those are (1) saturation pressure, (2) oil formation volume factor of bubble point liquid, (3) viscosity of gas-saturated crude oil, and (4) average compressibility of gas-undersaturated oil. As the result, it is found that, for the fluids in Japanese oil fields, the estimated values coincide fairly well with the measured ones.
