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.

COURSE DESCRIPTION


The course is designed to familiarize anyone using seismic data with the nature of the data and what it exactly 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 as a communication vehicle.

The course is supplemented by a large number of case histories that graphically 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 disk with several executable programs for parameter calculation and seismic modeling.

Potential participants in this course (BGP) should also review the description for the Seismic Imaging of Subsurface Geology course (SSD). The Basic Geophysics course is designed to provide participants with a clear understanding of the nature of the seismic image. Seismic Imaging is a foundation level course that is designed for people who will be involved directly in decisions concerning how seismic data are acquired and processed.

LEARNING OBJECTIVES


  • How seismic data represents subsurface rock parameters including the relative structure, lithology, and pore filling material
  • How seismic data is acquired and processed to produce a three dimensional seismic image
  • The limits of vertical and horizontal resolution inherent in the seismic data
  • How seismic data is used to define reservoir parameters and how it relates 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 technology including seismic inversion have helped us to define rock properties including pore filling material, pore pressure, water saturation, and fracture orientation
  • How to value the recent focus on developments such as time lapse seismic surveys for reservoir monitoring purposes
