“…While they observed changes of flow rates of shear-thinning and shear-thickening fluids, they found no effect from oscillations on the mean flow rate of a Bingham fluid. This observation contradicts a quasisteady analytical solution of Iassonov and Beresnev [6] that shows the mean flow rate amplifications for a Bingham fluid in the low-frequency limit.…”

Acoustic stimulation is a promising method for increasing drainage of non-Newtonian fluids through porous structures in various applications. In this study, a mathematical model is developed for unsteady flow of a bi-viscous incompressible fluid in a circular straight channel. Longitudinal vibrations are superimposed on the flow driven by changing pressure gradients along the channel. Simulations are carried out for a range of relevant dimensionless parameters. Effects of vibration amplitude, frequency, and fluid viscosity ratio on the enhancement of mean flow rate are discussed.

“…These features of the flow obtained from simple physical reasoning can be illustrated by the results of calculations using exact equations of fluid dynamics (Graham and Higdon, 2000) or simple model equations (Iassonov and Beresnev, 2003). For example, Figure 5 shows the flow rate of a spherical droplet (averaged over the cycles F osc /∇P s ) ≈ 1, "unplugging" corresponds to the total forcing equal to the unplugging threshold ∇P 0 , as we expected.…”

“…natural systems, and the possibility of their complex interactions, having such means is important. Iassonov and Beresnev (2003) use simpler model equations and a number of simplifying assumptions, which allowed them to obtain analytical solutions for the flow rate under the effect of vibrations. However, this work has a disadvantage of not considering the capillary geometry of the constricted flow that provides an explicit trapping mechanism.…”

In conjunction with Baker Atlas Inc. Michigan Technological University devised a system capable of recording the earth motion and pressure due to downhole and surface seismic sources. The essential elements of the system are 1) a borehole test site that will remain constant and is available all the time and for any length of time, 2) a downhole sonde that will itself remain constant and, because of its downhole digitization feature, does not require the wireline or surface recording components to remain constant, and 3) a set of procedures that ensures that the amplitude and frequency parameters of a wide range of sources can be compared with confidence.This system was used to record four seismic sources, three downhole sources and one surface source. A single activation of each of the downhole sources was not seen on time traces above the ambient noise, however, one sweep of the surface source, a small vertical vibrator, was easily seen in a time trace. One of the downhole sources was seen by means of a spike in its spectrum and a second downhole source was clearly seen after correlation and stacking. The surface vibrator produced a peak to peak particle motion signal of approximately 4.5 X 10 -5 cm/sec and a peak to peak pressure of approx. 2.5 X 10 -7 microPascals at a depth of 1,485 ft.

Theoretical work, some of it performed on this contract, gives us a glimpse of why that performance is so variable, namely it will work well only under a very narrow range of conditions, which rarely occur, although it will work weakly under a range of conditions, given a strong enough source.One of the many parameters needed in any performance analysis is the strength and frequency band of the seismic source being used to do the stimulation. Under this contract, we have begun a catalog of such sources by organizing the elements needed for rigorous testing and conducting four tests under identical conditions.In conjunction with Baker Atlas Inc.

“…The restoring force driving the oscillations is the surface tension force or capillary force. The fact that isolated oil blobs in residually saturated pore spaces can exhibit a resonance frequency, motivated the suggestion of a new enhanced oil recovery method (EOR) termed "wave stimulation of oil" or "vibratory mobilization" (Beresnev & Johnson, 1994;Iassonov & Beresnev, 2003;Beresnev et al, 2005;Li et al, 2005;Hilpert, 2007;Pride et al, 2008). Another example of oscillatory behavior within a medium is given by Urquizu and Correig (2004).…”
