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.

Coal permeability is regarded as one of the most critical parameters for the success of coalbed methane recovery. It is also a key parameter for enhanced coalbed methane recovery via CO2 and/or N2 ...

Compression ignition engines are required to operate over a wide temperature range and still maintain their high thermal efficiency. This requires the fuel injection system of the engine to operate at ...
