Sentence examples for saturation front from inspiring English sources

The total pressure was continuously increased by the evolution of the saturation front in the bentonite blocks and thereby the swelling pressure.

At low rates, the advance of the saturation front proceeds in a hyperdispersive manner, i.e., the water front spreads more rapidly than a tracer obeying normal (Gaussian) dispersion.

These tests include comparisons with available experimental data relative to a sand column desaturation and with the Philip's analytical solution for the propagation of a saturation front in an initially dry porous solid.

The capillarity pressure has little effect on the shape of the saturation front.

Open image in new window Fig. 6 Saturation front of tight oil and sand formation.

(2) Saturation front of tight formation moves faster than sandstone because of high capillary pressure.

Mesh adaptivity resolves saturation fronts in two regions of the column with high-resolution meshes and reduces the discretization error.

The risk of pressure-induced leakage from the aquifer can therefore be cast in terms of phase mobilities and speeds of saturation fronts.

In addition, the numerical saturation flood front does not exhibit the same piston-like displacement that is shown by the analytical solution.

It is found from Fig. 7 that the degree of water saturation at the front S BL is 0.51 and the average saturation behind the front is S w = 0.56; Fig. 8 illustrates the advance of water front for the horizontal square plane model (Fig. 5), calculated by the Buckley Leverett equation (Eq. 1).

The analytical solutions were in good agreement with recent mechanistic foam simulations in terms of foam texture, location of displacement front, saturation profile and pressure distribution.
