ABSTRACT

An experimental method for the determination of the bubble point pressure of crude oils has been developed using an acoustic wave sensor that consists of a Quartz Crystal Resonator. The basis of the method has been developed and measurements have been carried out with different types of systems including a transparent synthetic mixture, a bottomhole oil from North Sea and a live crude oil with addition of nitrogen. The efficiency of the method has been tested by comparing the results with those obtained with traditional PVT techniques and with direct visual observation of the bubble conditions for the synthetic system.
