Addressing the term "nano-Darcy": Does it make sense?

Darcy - by itself - refers to a porous system at the macroscopic scale; and it emphasizes strongly that we are NOT supposed to look at the details - even - at the microscopic-scale. Given this...

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...

The "permeability-loss" and the "permeability-gain" in a typical CBM reservoir - nearly have equal magnitudes?

The "permeability-loss" term is associated with pressure depletion, while the "permeability-gain" is associated with the coal-matrix shrinkage in a CBM Reservoir. Both are expected to occur...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
