ABSTRACT:
The present invention is a high-pressure sapphire cell designed to measure the properties of a petroleum reservoir fluid sample. It comprises at least two sapphire anvils, a pressure vessel having inlet and outlet parts, gaskets between the anvils and the pressure vessel; and a means for forcing the anvils together to form a fluid-tight seal between the anvils and the pressure vessel. Once a fluid sample enters the pressure vessel, a high pressure environment similar to a petroleum reservoir is created by an outside pressure pump via a pressure inlet tube. It is in this state that the fluid measurements are made on the sample.
