Description

Designed for you, if you are...

• A geologist, geophysicist or engineer working in development & production petroleum geology

How we build your confidence

• The course is integrated with practical exercises and real case studies to enhance the understanding of petroleum geochemical analytical techniques, data acquisition and data interpretation.
• Extensive practical exercises and real case studies are conducted during the course to enhance the understanding of different techniques, their implementations and - importantly - some of the limitations of such data.

The benefits from attending

• Become familiar with the key analytical techniques of reservoir geochemistry
• Evaluate the processes related to preservation of organic matter in sedimentary environments
• Have an overview of characteristics of kerogen and petroleum and conversion of kerogen to hydrocarbons
• Learn how key geochemical data are generated
• Have a solid foundation for interpreting geochemical data from basic source rock characterisation to oil/oil and oil/source correlation
• Become familiar with some of the basic concepts of maturity modelling
• Integrate data with conceptual models to develop interpretation
• Through practical sessions learn how to handle different types of data and especially the limitations of each type of analyses and the benefits of integration of differing types of data
• Examine in detail how geochemical data can be used in recognising and assessing reservoir continuity, alteration with reservoir, migration pathways and compartmentalised accumulations
• Have an overview of other techniques not directly related to hydrocarbons (metal and water analyses)
