“…Laboratory work on the direct verification of mobilization phenomena in controlled environments (e. g., Roberts et al, 2001;Poesio et al, 2002) should be continued. This creates a test ground for the existing theories of flow enhancement by vibrations, including this one.…”

“…It is well known that, even after water flooding, on average two thirds of the oil remains entrapped in the reservoir in form of isolated ganglia (or "blobs") (e.g., Payatakes, 1982). The possibility of vibratory mobilization of the residual oil has received much attention over the last years, mostly due to its potential low cost and environmental friendliness (e. g., Beresnev and Johnson, 1994;Hilpert et al, 2000;Roberts et al, 2001Roberts et al, , 2003Poesio et al, 2002). With field tests proceeding around the world and mixed results being their most consistent feature, the question that has often been asked is why low-frequency vibrations should mobilize the residual oil?…”

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.

“…This reduction was supposed due to the medium heating by ultrasound absorption. In addition, Poesio et al [4] studied the effect of acoustic waves on flow of fluid through sandstone core samples and observed a decrease of pressure drop inside the core samples by acoustic waves. They related this phenomenon to the fluid viscosity reduction.…”

Ultrasound technique is one of the unconventional enhanced oil recovery methods which has been of interest for more than six decades. However, the majority of the oil recovery mechanisms under ultrasound reported in the previous studies are theoretical. Emulsification is one of the mechanisms happening at the interface of oil and water in porous media under ultrasound. Oppositely, ultrasound is one of the techniques using in oil industry for demulsification of oil/water emulsion. Therefore, the conditions in which emulsification becomes dominant over demulsification under ultrasound should be more investigated. Duration of ultrasound radiation could be one of the factors affecting emulsification and demulsification processes. In this study a technique was developed to investigate the effect of long and short period of ultrasound radiation on emulsification and demulsification of paraffin oil and surfactant solution in porous media. For this purpose, the 2D glass Hele-shaw models were placed inside the ultrasonic bath under long and short period of radiation of ultrasound. A microscope was used above the model for microscopic studies on the interface of oil and water. Diffusion of phases and formation of emulsion were observed in both long and short period of application of ultrasound at the beginning of ultrasound radiation. However, by passing time, demulsification and coalescence of brine droplets inside emulsion was initiated in long period of ultrasound application. Therefore, it was concluded that emulsification could be one of the significant oil recovery mechanisms happening in porous media under short period of application of ultrasound.

Theoretically, ultrasound method is an economical and environmentally friendly or "green" technology, which has been of interest for the purpose of enhancement of oil/heavy-oil production. However, in spite of many studies, questions about the effective mechanisms causing increase in oil recovery still existed. One of the changes that could be recognized in the fluid properties is viscosity reduction due to radiation of ultrasound waves. In this study, a technique was developed to directly investigate the effect of ultrasonic waves (frequencies of 25, and 68 kHz and powers of 100, 250, 500 W) on viscosity changes of Paraffin, Synthetic oil, and Kerosene. The experiments were carried out for uncontrolled and controlled temperature conditions in a smooth capillary tube. The viscosity of all the liquids was decreased under ultrasound in all the experiments. Cavitation and heat generation are identified as influencing mechanisms on oil viscosity reduction under ultrasound. The effect of ultrasound frequency, power and temperature on viscosity reduction is also discussed in this article.
