Two separate correlations for predicting the isothermal compressibility of reservoir fluids and crude oils have been developed. One correlation is based on molecular weight; the other, on API gravity.

This article presents an easy and simple spreadsheet procedure for custody-transfer calculations of the base compressibility factor for any pair of pressure and temperature conditions. The procedure ...

Pressure waves propagating through bubble-containing liquids in tubes experience considerable attenuation. Researchers have now derived an equation describing this phenomenon, demonstrating that ...
