    The Mechanical Earth Model and Wellbore Stability course is a RILS (remote instructor led training) delivered in real time. The course will be delivered in 4 hour segments over a 3 day period and is delivered using the WebEx platform

    This course is designed to introduce geomechanics workflows that are used to build wellbore-centric Mechanical Earth Models (1D MEM). The course will combine virtual lectures with short software demonstrations. The theoretical foundation to understand wellbore geomechanics is introduced by lectures on the state of stress in the earth, pore pressure, rock mechanics properties and their measurements, as well as the application of a 1D MEM to wellbore stability analysis.

    The course will be delivered in 3 virtual sessions of 4 hours each. The first session introduces the fundamentals of well-centric petroleum geomechanics and begins to build a mechanical earth model by discussing overburden stress and pore pressure. The second session then discusses how to model rock mechanical proeprties and horizontal stress to finalize the mechanical earth model The third session then puts it all together in a wellbore stability analysis that also shows the calibration of a 1D mechanical earth model with observed wellbore instability.

    At the end of the course attendees will be able to:

    1. Understand the basic workflow to build and calibrate 1D Mechanical Earth models
    2. Understand the data requirements for 1D Geomechanics studies
    3. Understand the use of the Mechanical Earth Model in geomechanical studies
