To test the variation in permeability and strength parameters of various foam cements, stepwise loading and unloading experiments were conducted. Effective pressures varied between ≈6.8 MPa to ≈46 MPa...

... to hours, depending on the characteristics of the sample. This allows the permeability measurements to be performed as many time as need to produce repeatable results. Furthermore, the absolute permeability of the sample can be calculated by applying the gas slippage (Klinkenberg) and/or gas double...

... presents the experimental comparison of three different unsteady-state transient methods for measuring the permeability of organic-rich shale plugs: pressure build-up, pulse-decay and oscillating pulse techniques. Permeability measurements are conducted isothermally using nitrogen gas on core plugs from...

Exerting a backpressure at the outlet of the core sample is the key to diminish the gas slippage effect. When the backpressure reaches a certain value, defined...

...-pressure drop criteria. Permeability measurement on 10 nano-darcy to 10 micro-darcy permeability core plugs, under 400 to 5000 psi, is feasible and repeatable with a reasonable uncertainty range, at qualified commercial laboratories. Porosity data showed uncertainties in the range of ±1.0 p.u...

... dioxide. Porosity and permeability measurements are conducted using various techniques including numerical simulation that incorporates detailed measurements of the in-situ, core-scale porosity distribution. The research simulator is fully implicit, finite volume, unconditionally stable, and incorporates...

.... Porosity and permeability measurements were carried out using several gases including He, N 2 , CH 4 and CO 2 over a wide range of pore pressures. The storage capacity of helium was in fact lower than that of CH 4 . This comparison with different gases also shows a decreased permeability as we move...

From a permeability standpoint, unconventional reservoirs are usually too tight to allow for steady-state permeability measurements, and microfracturing is often too pervasive to allow for reliable permeability measurements on whole plug samples. As a result, we have...
