    Geochemistry & Petroleum Systems

    The aim of our training courses is to provide geoscientists and engineers with an understanding of how petroleum geochemistry and basin modelling can solve many oil and gas exploration and production problems, both for conventional and unconventional plays. The overarching objective is to introduce the fundamentals of Petroleum Geochemistry and, following on from this, equip the candidates to go into greater depth on topics that they are particularly interested in​.

    The course is composed of three keystone modules which are of longer length than the others:​

    The keystone module on Source Rocks is concerned with petroleum source rocks, how they are characterized, how they are formed, how they evolve with increasing maturation, and how this influences the types and volumes of petroleum generated from different types of source rocks at different maturities.​

    The keystone module Petroleum is concerned with how petroleum is formed and characterized, the controls on petroleum composition prior to and after it enters the reservoir, and how petroleum can be grouped into genetic families and correlated to their source rocks.​

    The keystone module Petroleum Systems Analysis & Basin Modelling introduces the concepts and types of petroleum systems analysis and basin modelling, what input data is required, how models are constructed, the types of outputs and sensitivity analysis​

    ​Supplementary modules provide more insight on different applications of petroleum geochemistry, these include Organic Petrology & Maturity, Reservoir geochemistry, and Well site gas – fundamentals and applications
