WebJan 3, 2024 · Significance and Use. 5.1 The seismic downhole method provides a designer with information pertinent to the seismic wave velocities of the materials in question (1). The P-wave and S-wave velocities are directly related to the important geotechnical elastic constants of Poisson’s ratio, shear modulus, bulk modulus, and Young’s modulus. WebMar 27, 2013 · Seismic testing is commonly used for many resource extraction processes, including mining and oil and gas. Seismic testing is used specifically to map the underlying geology in order to determine if the proper formations exist for further exploration. Two methods are used — explosives or vibriose trucks (often known as thumper trucks). WebThe Crosshole Seismic (CS) system and method determine shear and compressional wave velocity versus depth profiles. From these measurements, parameters, such as Poisson’s ratios and moduli, can be easily determined. In addition, the material damping can be determined from CS tests. rebecca anwar
