This book was released on 1990 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigation of ultrasonic waves, especially the slow compressional wave, with fluid-saturated porous solids, especially rocks. This research effort should fine applications in the geophysical evaluation of fluid-bearing porous rocks where parameters such as tortuosity, permeability, saturation level, and internal impurities are difficult to measure by conventional techniques. The proposed investigation may be divided into three major subtasks: Experimental study of surface wave propagation on fluid-saturated porous materials. A new, so-called direct excitation technique will be used on both air- and water-saturated samples; further development of the Lamb wave technique recently introduced to study guided wave propagation in thin fluid-saturated porous plates. The analytical treatment will be extended to account for viscous losses and scattering inhomogeneities; and theoretical and experimental study of slow wave propagation in fluid-saturated natural rocks. A new technique based on the transmission of airborne ultrasound through air-saturated porous plates will be used to determine properties such as tortuosity, permeability, etc. 22 refs., 37 figs., 3 tabs.

This book was released on 1992 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last two years we have continued our investigation of ultrasonic wave propagation in fluid-filled porous materials. First, we studied the feasibility of using different surface modes to characterize both synthetic and natural rocks. We introduced a novel experimental technique based on the direct generation of surface waves by edge excitation. We used two low-frequency (100--500 kHz) shear transducers in pitch-catch mode to launch and receive the ultrasonic surface wave. The contact transducers were coupled to the opposite edges of the porous specimens with normal polarization relative to the surface. The same technique was successfully used to generate Rayleigh-type surface modes on the free surface of both dry and water-saturated specimens, as well as Stoneley-type interface modes on the fluid-loaded surfaces of immersed samples. Our main achievement in this area is the realization that, due to surface tension, practically closed-pore boundary conditions can prevail on the free surface of a water-saturated rock for completely open pores. As a result, the velocity of the true surface mode might be much lower than the Rayleigh velocity of the dry skeleton.

Previously, we studied the feasibility of using different surface modes to characterize both synthetic and natural rocks. We introduced a novel experimental technique based on the direct generation of surface waves by edge excitation. At first, we used two low-frequency (100--500 kHz) shear transducers in pitch-catch mode to launch and receive the ultrasonic surface wave. The contact transducers were coupled to the opposite edges of the porous specimens with normal polarization relative to the surface. The same technique was successfully used to generate Rayleigh-type surface modes on the free surface of both dry and water-saturated specimens, as well as Stoneley-type interface modes on the fluid-loaded surfaces of immersed samples. Recently, we developed a special interferometric technique for non-contact detection of ultrasonic vibrations on diffusely reflecting rough surfaces. This method was found to be more suitable for surface wave inspection of porous ceramics and natural rocks than the previously used contact techniques. Beside investigating guided acoustic waves in water-saturated porous materials, we also studied bulk wave propagation in air-saturated specimens. We further developed our experimental technique which is based on the transmission of airborne ultrasonic waves through air-filled porous plates. This method can be readily used to study the frequency-dependent propagation properties of slow compressional waves in different porous materials including natural rocks. By simple technical improvements, we extended the measuring range so that we could continuously cover both low-frequency (diffuse) and high-frequency (propagating) regimes of slow wave propagation.

This book was released on 2019-09-25 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a study that establishes a set of diagnostic parameters for characterizing the behavior of a geological medium stimulated by external fields and their interactions as a physical basis for developing new methods in exploration geophysics. It describes in detail the investigation methods and instruments (including laboratory, field and borehole devices), and discusses experimental, field and modeling investigations of the interaction of mechanic/electromagnetic fields in reservoir rocks. Lastly, the book also evaluates and the proposed methodology and demonstrates its effectiveness using case studies in which certain geophysical diagnostic/exploration problems have been solved.
