This course is designed to provide an overview of one of the most important factors that determine the success or failure of an oil & gas project, this highly interactive program will equip you with a fundamental understanding of:

• • The terminology, jargon and procedures used in seismic geophysics
  • The strengths and limitations of the seismic method in Oil & Gas operations
  • How 2D, 3D and 4D surveys are economically justified, acquired, processed and interpreted
  • The construction, meaning and use of seismic maps and sections
  • An overview of the latest technological developments in seismic geophysics

By the end of this course delegates will be able to:

• • Obtain an understanding of the strengths and limitations of the seismic method, and the costs and risks involved, and how to reduce these
  • Be able to communicate more effectively with petroleum geophysicists
  • Understand the meaning of seismic maps and sections and know how to judge the quality and limitations of these important exploration tools
  • Gain an overview of the latest developments in seismic technology
  • Apply new-found knowledge to a series of simple illustrative exercises to aid understanding and gain confidence in use
  • Know what types of questions to ask in order to assess the quality of a seismic project
