The Acoustics Special Interest Group has been formed in accordance with SPWLA bylaws and has been ratified/approved by the committee. The purpose of this SIG is to provide a forum for those interested in borehole acoustics to conduct technical discussions concerning tool design, data acquisition, applications, interpretation, and to develop/promote industry standards.
Borehole Acoustics has grown significantly in technology and applications since the early days of monopole wireline tools in the 1960s. There have been design advances in both the wireline and LWD systems allowing for ever-increasing data quality and complexity. Uses of the data have grown from porosity and cement bond logging to include pore pressure prediction, seismic correlation, 3D stress profiling, fracture characterization, production enhancement, permeability, geosteering, and more.
The complexity of acoustic data and number of applications which require high levels of processing skill have led to some frustrations in the industry about understanding accuracies and uncertainties. Different vendors can have quite different processing methods and data delivery techniques, leading to apparent conflicts in results. An acoustics SIG is a vehicle to develop or suggest industry-wide standards for processing, data delivery, and log displays (where appropriate).
The SIG should be an excellent vehicle for discussions of existing and emerging applications and validation of new techniques. Some benchmark test cases could be organized for emerging tools and applications. Membership is open to all, with participation welcome from operators, service companies, academia, and consultants. There is no fee to join the SIG (though there is sometimes a registration fee to attend meetings in order to offset the cost of meeting facilities/meals).
