Numerical Simulation Of The Acoustic And Elastic Wavefields Radiated By A Source In A Fluid-Filled Borehole Embedded In A Layered Medium
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1992)We present a method of calculation to simulate the propagation of acoustic and elastic waves generated by a borehole source embedded in a layered medium. The method is formulated as a boundary element technique where the ... -
Radiation Patterns Of Compressional And Shear Transducers At The Surface Of An Elastic Half Space
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1992)The radiation patterns of an elastic wave field generated by circular plane compressional and shear transducers are derived using the method of steepest descent. These patterns contain both effects of the elastic half ... -
Experimental And Finite Difference Modelling Of Borehole Mach Waves
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1992)A series of model experiments are done in the ultrasonic laboratory to study the radiation of downhole sources in a variety of formations. Three models are used in the experiments. They are a lucite model, a lucite model ...
