Bounds for seismic dispersion and attenuation in poroelastic rocks
Recently, Hashin-Shtrikman bounds for bulk and shear moduli of elastic composites have been extended to the moduli of composite viscoelastic media. Since viscoelastic moduli are complex, the viscoelastic bounds form a closed curve on a complex plane. We apply these general viscoelastic bounds to a particular case of a porous solid saturated with a Newtonian fluid. Our analysis shows that for po...
متن کاملAnisotropic attenuation analysis of crosshole data generated during hydraulic fracturing
A of seismic waves is sensitive to the physical properties of the subsurface and has been observed in vertical seismic profiling (VSP) and reflection data. De et al. (1994) report measurements of the Pand S-wave quality factors from VSP surveys and sonic logs. Klimentos (1995) measures compressional and shear attenuation from sonic logs in sandstone formations with variable oil, water, and gas...
متن کاملSedimentation and Sedimentary Rocks
Sedimentary rocks are one component of the modern threefold classification of rocks. They derive from the lithification of sediments, which are produced in basically two ways: by the mechanical deposition of grains derived from the alteration of other rocks (detrital or clastic rocks), or as chemical precipitates or grains formed organically or inorganically from an aqueous solution. The whole ...
متن کاملCrosshole seismic tomography with cross-firing geometry
We have developed a case study of crosshole seismic tomography with a cross-firing geometry in which seismic sources were placed in two vertical boreholes alternatingly and receiver arrays were placed in another vertical borehole. There are two crosshole seismic data sets in a conventional sense. These two data sets are used jointly in seismic tomography. Because the local sediment is dominated...
متن کاملa study of baudrillards ideas in brian moores fiction
پیدایش مرحله ی جدیدی از نظام سرمایه داری بعد از جنگ جهانی دوم همزمان است با ظهور عصر اطلاعات و رسانه جمعی. در چنین جامعه ای سیر آزادانه ی نشانه ها در فضای بی اساس مجازی بر سرعت فرسایش واقعیت می افزاید. به اعتقاد بودریار، فقدان واقعیت به واسطه ی شبیه سازی آن و تولید حاد واقعیت (hyperreality) پنهان خواهد ماند. این پژوهش بر آن است که جامعه فرانوین توصیف شده در سه رمان بریان مور را با توجه به نظر...
