Clastic Sedimentation and Sequence Stratigraphy (GEO69)


    This course provides a detailed overview of common clastic sedimentary systems and how the reservoir characteristics of the resulting deposits are controlled by the combination of their depositional environment and sequence stratigraphic setting. A good understanding of these key controls on the distribution, size and shape of clastic reservoir and non-reservoir rocks as well as their internal properties, is of fundamental importance to sound reservoir characterisation and consequently to Exploration & Production decision-making. This applies throughout the hydrocarbon resource life-cycle, all the way from exploration, through appraisal, to development and eventually abandonment.

    Course Level: Skill
    Duration: 5 days
    Instructor: Evert van de Graaff

    Designed for you, if you are...

    • A petroleum geoscientist or petroleum engineer in the initial phase of your E&P career, who needs to be fully conversant with sedimentology and stratigraphy as key tools in the oil & gas industry

    How we build your confidence

    The course uses a combination of lectures and paper exercises. The exercises are mostly built around correlation problems to highlight the importance of using sound sedimentological and stratigraphic concepts for building fit-for-purpose subsurface models.

    In addition to the course manual participants will receive a copy of the textbook 'Sedimentology and Stratigraphy'.

    The benefits from attending

    By the end of the course you will be able to:

    • Describe the main characteristics of common clastic reservoir types and how these characteristics are controlled by the combination of depositional origin and sequence stratigraphic setting
    • Identify the key practical implications of the inferred reservoir characteristics, both for your own discipline and for the E&P project as a whole
    • Communicate effectively about these technical issues with the other disciplines involved in the E&P project
    • Contribute effectively to managing and mitigating risks to exploration and/or development activities in E&P projects
