Duration : 20 hours

Level : Advanced

WHO SHOULD ATTEND: Drillers, drilling engineers, operation geologists, geophysicists and petroleum engineers who want to expand their knowledge of how geomechanical rock properties and stresses affect the stability and integrity of wellbores from the design phase to the drilling and production phases of well construction.

OBJECTIVES: This workshop presents field examples and laboratory experiments at an advanced level to illustrate the concepts and practical applications of geomechanical theory to well construction and production challenges.

BENEFITS:

You will learn how to use geomechanics theory to understand the effects of drilling practice on wellbore stability and how to treat instability during well construction.

You will be able to estimate the well pressure limits to design drilling programmes and avoid wellbore instability – breakout, breakdown and other hazards and unconventional failures.

You will learn of advanced techniques to optimize drilling performance and mitigate against drilling hazards in unconventional situations.

Course content includes:

• Essential rock mechanics and laboratory measurements of rock elastic and failure properties
• Construction of a rock mechanical earth model for the prediction of wellbore instability, accounting for anisotropic shales and earth stresses – understanding Leak-off tests
• Evaluating limits to wellbore stability for specific well trajectories and the selection of mud weights
• Planning for wellbore stability – case studies illustrating the use of formation evaluation data to manage common wellbore instabilities
• Reservoir geomechanics – instability in reservoir and overburden generated by pore pressure depletion, temperature changes and injection of CO₂
• The geomechanics of drill bit design and using mechanical specific energy (MSE) to optimize drilling performance
• Understanding and mitigating against the causes of lost circulation while drilling and cementing
• The geomechanical implications of drilling naturally fractured intervals and the creation of induced fractures
• The principles of wellbore strengthening techniques for drilling depleted intervals
