Petroleum Geoscience

An In-Person Training Course by Esanda.


    In-House sessions are available upon request.

    Course Overview:

    This is a course for non-specialists and no prior knowledge of Earth sciences is necessary. The aim of the course is 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.


    The Course Is Designed For:

    Non-Earth scientists with little or no background in geology, geophysics or the processes that control the formation and distribution of oil and gas resources.


    Learning Objectives:

    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.


    Your Instructor:

    Michael AlaDr. Michael Ala

    Dr Michael Ala has been closely associated with the oil industry for more than 35 years as an exploration geologist with an independent oil company, a consultant, provider of training programmes worldwide and an academic at Imperial College since 1981. His main interests include basin studies, controls on the occurrence and global distribution of both conventional and unconventional oil and gas resources. His publications include more than 60 research and review articles and he remains engaged in the industry, holding non-executive directorships with companies involved in exploration and oil and gas field development activities in North Africa and Middle East.
