Introduction to Geomechanics (GEO52)

    Description

    This course introduces basic reservoir geomechanics concepts and methods to enable cross-disciplinary exchange of ideas and experience. It provides the required input to help you understand questions crucial to the reservoir Geomechanics: How human activities of drilling, production and injection can affect the stress equilibrium in the reservoir at depth? How these changes in the stresses can create different problems? How can we drill without surprises? Where to place horizontal wells for better production? How and what completion methods can be used to optimise the production? What reservoir/field development plan is optimum for better production over reservoir lifecycle?

    Course Level: Foundation
    Instructor: Manhal Sirat

    Designed for you, if you are...

    • A geoscientist or engineer with little or no reservoir Geomechanics experience

    How we build your confidence

    • Theoretical concepts illustrated during individual sessions are accompanied by working on practical problems to ensure a thorough understanding of the principles and procedures
    • Hands-on experience by solving classical reservoir Geomechanics tasks

    The benefits from attending

    By the end of the course you will feel confident in your understanding of:

    • Reservoir Geomechanics concepts and terminology
    • The 3D stress state in the subsurface
    • Principles of rock mechanics
    • The interrelations among 3D stress state, the natural and induced fractures and fluid flow
    • What factors control fracture/fault reactivation with possible predictions
    • Typical assumptions and simplifications required to predict reservoir behavior under different states of stress

    Topics

    • Introduction to the physics of petroleum reservoirs
    • Fractures and the 3D state of stress
    • Andersonian classification of faults and stress regimes
    • Fundamental rock mechanics – Uniaxial and Triaxial tests, mechanical and elastic properties and other concepts
    • Hoop stresses and wellbore deformation
    • Pore pressure and stress changes and their effects on reservoirs and petroleum E&P
    • Building 1D MEM and 3D MEM (Mechanical Earth Model)
    • Implications and case studies
