Abstract
ABSTRACT A series of experiments were carried out in the laboratory on acoustic wave velocities in oils. The samples include 8 dead crude oils (here dead oil refers to stock tank oil which does not contain dissolved gas), 2 refined petroleum hydrocarbons, and 1 live oil (here live oil refers to oil which has high content of dissolved gas). The results show that the measured acoustic velocities in these oils are strong functions of both temperature and pressure. The experimental results are discussed in light of the various existing theories and models of the liquid state for the purpose of interpreting and understanding the acoustic velocity behaviors of the oils. Correlations are made between the acoustic velocity and temperature, pressure, API gravity, and molecular weight. Empirical equations are established which can be used to calculate the acoustic velocities in oils with known API gravities. Various applications or potential applications of the experimental results are also discussed.
