Course Description

Petroleum Geoscience for Non-Specialists Workshop

Duration: 4 days

  • Presenter: Dr Michael Ala (Imperial College London)
  • Prerequisites: This is a course for non-specialists and no prior knowledge of Earth sciences is necessary.
  • Aims: To cover the fundamentals of the Earth sciences, examine their role in controlling the occurrence, distribution and quantification of ‘conventional’ oil and gas reserves; review the ‘non-conventional’ hydrocarbon resources; provide an introduction to the ‘peak oil’ debate.
  • Who should attend? Non-Earth scientists with little or no background in geology, geophysics or the processes that control the formation and distribution of oil and oil and gas resources.

 

Learning Outcomes: The course presents the principles and practices underpinning the Earth sciences and demonstrates how they can be applied to hydrocarbon exploration and production. The participants will gain an understanding of the factors and processes involved in the formation of oil and gas fields and their worldwide distribution.
