This talk will discuss the nature of recent changes in the seismic industry and the benefits that have resulted. Improvements have been made in recording technology and equipment and these have enabled newer and greatly improved methods of recording data. The increased power of computing systems has allowed efficient data processing of the extremely large data volumes that are now being recorded and new data processing and analysis methods are permitting the extraction of information that would have been considered impossible just a few years ago. Geographical variations in the utilization methods will also be discussed.



About the Author(s)

R. Malcolm Lansley received a B.Sc./A.R.C.S. in physics/mathematics/geophysics from Imperial College of Science and Technology in London in 1969. Six years ago Malcolm joined Sercel as VP of Geophysics, where he advises on the geophysical usage of all Sercel equipment including survey design, data collection, data processing, and interpretability of the resultant data. Prior to joining Sercel he had worked for more than 35 years with Geophysical Service, Inc., Halliburton Geophysical Services, Western Geophysical and PGS in all areas of the world, both onshore and offshore. Although he started working with 2D in 1969, his first involvement with 3D seismic exploration was in 1972, and since that time he has been concerned with all aspects of 2D and 3D seismic exploration from survey design, through data acquisition and data processing, to interpretation.

Malcolm has authored more than 50 papers on seismic exploration, data processing and interpretation. His research interests include 3D technology (both land and marine,) marine data acquisition, wavelet processing, and vibrator theory and usage. He also teaches a variety of courses on vibrator theory and usage, 3D survey design, data acquisition and data processing for SEG. He is a member of SEG, EAGE, CSEG, ASEG, RMAG, SBGf and the Geophysical Society of Houston. He is also a licensed/registered Professional Geophysicist (#5655) with the Texas Board of Professional Geoscientists.
