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 measurements through casing and cement evaluation. The field has recently even expanded beyond the near wellbore, to image events far from the wellbore itself and moved outside of traditional oil and gas applications, such as becoming a key part of successful CCUS projects. The Acoustics SIG is a community of people from a wide variety of disciplines within both the oil and gas and alternative energy communities, who all share a common interest in the science of borehole acoustics. Our membership ranges from those with just a technical curiosity to those who are specialists in the field, and includes members from academia, governmental organizations, and the corporate world. We are open to people of all backgrounds and there are no fees associated with joining the SIG, although we obviously encourage you to also join the SPWLA. We endeavor to meet once every two months, as well as to have periodic workshops.
