Instructor: Malcom Lansley
Date: November 15 – 16, 2012

Venue: TBA
Time: TBA

Audience:

This course is intended for geoscientists involved in the use of seismic data. It is appropriate not only for geophysicists and geologists involved in survey design and acquisition, but also for those involved in data processing and interpretation who wish to better understand the potential improvements that can be made with the use of new technologies.

Course Description:

This course will provide information related to recent advances in data acquisition technology, equipment and the methodologies that are being utilized to improve data quality and, in many cases, reduce the cost of 3D survey acquisition. Both marine and land applications will be discussed.

The course will not cover the fundamentals of data acquisition or 3D survey design, although there will be a short section that will discuss some of the problems and errors that are frequently made in some of the surveys being acquired today.

Topics discussed in the course include:

  • Introduction, including cost-benefit overview
  • Design issues frequently misunderstood, forgotten or deliberately ignored
  • Wide azimuth vs narrow azimuth geometries
  • The search for low frequencies, including dual sensor marine data acquisition
  • Marine simultaneous sourcing
  • High density surveys
  • Where cable-less recording systems are applicable and where not
  • Modern land source technology, including high productivity vibroseis methodologies
  • Arrays versus point receivers
  • 3C sensors versus conventional p-wave geophones

 

Presenter / Instructor Biography:

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, and 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.

Mr. Lansley 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.
