Spwla Acoustics Sig

the purpose of the acoustics sig is to promote the science and application of borehole acoustics within the wider petrophysical community and to provide an open forum for members to discuss the latest developments within the field. borehole acoustics has grown significantly in technology and applications since the early days in the 1960's. it now encompasses a wide field of disciplines within geophysics, petrophysics, geomechanics and well integrity, and the technology has developed from the simple early tools to today’s complex, full-waveform wireline and lwd devices. modern borehole acoustics deals with the excitation, detection and interpretation of multiple types of propagating arrivals to determine a diverse set of information about the formations surrounding the borehole including porosity, lithology, fluid typing, rock mechanical properties, anisotropy, stress state, pore pressure, permeability, fracture analysis and more. it also covers cased hole evaluation, both formation
