Because most sedimentary rocks encountered in oil and gas exploration are effectively anisotropic, it is imperative to properly estimate seismic anisotropy and incorporate it into data-processing and imaging algorithms. Seismology of Azimuthally Anisotropic Media and Seismic Fracture Characterization (SEG Geophysical References Series No. 17) presents a systematic analysis of seismic signatures for azimuthally anisotropic media and describes anisotropic inversion/processing methods for wide-azimuth reflection data and VSP (vertical seismic profiling) surveys. The main focus is on kinematic...

Over the past decade, microseismic monitoring, a technology used to evaluate the completions of wells drilled to produce hydrocarbons from unconventional reservoirs, has grown increasingly popular among oil and gas companies. Microseismic Monitoring, by Vladimir Grechka and Werner M. Heigl, presents a thorough description of how to process microseismic data and the underlying theory, of what can and cannot be inferred, and to what level of certainty. The layout of the book follows the passage of a seismic wave - from a source triggered by hydraulic stimulation, through hydrocarbon-bearing...
