Basic Geophysics

This course is designed to familiarize anyone using seismic data with the nature of the data and what it specifically represents. One of the key goals of the course is to explain the large and confusing amount of "jargon" that is used by the Geophysical community when they use seismic data.

The course is supplemented by a large number of case histories that concretely illustrate the principles in the course material. These are updated with every course presentation to keep up with the rapidly developing technology in this field. Each section of the course is supported with a classroom exercise. The course participants are given a data-thumb drive that contains the case histories, class exercises and all of the extensive PowerPoint animations used in the classroom.

Who should attend? Geoscientists, engineers, team leaders, geoscience technicians, asset managers, and anyone involved in using seismic data that needs to understand and use this data as a communication vehicle.

Learning outcomes: 

  • How seismic data represent subsurface rock parameters including the relative structure, lithology, and pore filling material
  • How land and marine seismic data are acquired and processed to produce both a two and three dimensional seismic image
  • The limits of vertical and horizontal resolution inherent in the seismic data
  • How seismic data are used to measure reservoir parameters and how data relate to reservoir development; this includes a detailed discussion of AVO and other seismic attributes
  • The various approaches to seismic imaging and how the velocity model relates to this image
  • How new technologies including seismic inversion have helped us to define rock properties including pore filling material, pore pressure, water saturation, and fracture orientation
  • How to value developments such as time lapse seismic surveys for reservoir monitoring purposes
