Mechanical Earth Model Building

The Mechanical Earth Model Building course is a VILT (virtually instructor led training) delivered in real time. The course will be delivered in 4 hour segments over a 2 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 2 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, pore pressure and rock mechanical properties. The second session then discusses horizontal stress to finalize the mechanical earth model and puts it all together in a wellbore stability analysis

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

    Day 2

    Horizontal Stress, Wellbore stability and the Mechanical Earth Model (4 hours)

    • Principal stresses in the earth (overburden stress, horizontal stress orientation, horizontal stress magnitudes) and their determination in the 1D MEM
    • Wellbore stability, state of stress in the wellbore, modes of failure and rock deformation in the wellbore, calculation of wellbore stability and effect of well azimuth and inclination
