Diffusivity equation for describing oil flow in a petroleum reservoir: Can it be assumed to be an incompressible fluid?

Diffusivity equation for describing oil flow through a petroleum reservoir is deduced by coupling mass and momentum conservation equations. In many cases, the oil flow within the reservoir is...
