Course Overview

The objective of Merlin’s 4-day Geomechanics for Drilling Engineers training course is to provide experienced personnel with an understanding of all aspects of geomechanics as it relates to well construction activities. The course is designed to ensure delegates end up with a suitable level of knowledge to allow them to account for wellbore stability related factors at the well planning stage, allowing wellbore stability problems to be minimised through fit-for-purpose design during the engineering phase and through procedure when executing a well construction project. The course is intended to be of practical use, with a focus on real-world examples and case studies, rather than the mathematics behind the subject.

Upskill with Merlin and learn to drill further, faster, more efficiently.

Invest in yourself, your team and ultimately your results by attending Merlin’s Geomechanics Training Course.

What will I learn?

  • The importance of understanding subsurface stress regimes and what can happen if these are ignored in well planning.
  • How a geomechanical is built and calibrated.
  • Fundamental features of the models.
  • How the wellbore interacts with the subsurface stress field.
  • How to optimise the well design and execution plan based on the model outputs.
  • Benefits of real-time monitoring and model updating to optimize the drilling program.

Example Schedule

Engineering

Geomechanical problems can significantly contribute to drilling related NPT. Understanding the risks through modelling is integral to effective well design and to successfully drilling wells with complex geometries or those that are in challenging geological environments.

Operations

Execution is make-or-break time. Effort and energy expended during planning needs to be harnessed and directed to assure operational success. Merlin can support your field operations with people that have real expertise and experience, and have the know-how and energy to drive success within your team.
