摘要
Techniques for evaluating physical aspects of a formation fluid from within a wellbore include changing at least one of a pressure on and a temperature of a sample of the formation fluid and transmitting at least one acoustic pulse through the fluid sample and analyzing acoustic information collected. Apparatus and methods for the evaluating involve using at least one acoustic transducer. Analyzing typically involves use of formulae that relate equation (s) of state and other properties for the fluid to a change in the sound speed in the fluid.
