Full-Wave Imaging

摘要

There's no argument about the crucial role that technology plays for prospec-tors.Some developments are afoot that are opening up supplemental information about the subsurface,and explorers are eager to see the advantages these may bring."The next turn of the crank in geophysics is going to come from full-wave imaging,"says Chris Friedemann,vice president of commercial development for Input/Output.Full-wave imaging provides a clearer view of the subsurface by adding shear-wave data to the compressional-wave data that the industry has traditionally acquired.These shear-wave measurements can be converted waves from a compressional source,or direct measurements from an active shear-wave source.
