Geomechanical Analysis-Mitigating Against Compaction Related Casing Damage -OG 8012

7th June - 11th June 2021 (London, UK) 6th September - 10th September 2021 (Dubai, UAE) 22nd November - 26th November 2021 (Houston, Texas, USA.)

Course Overview

The basic approach to geotechnical analysis is to use what datasets are available for interpretation of rock strength, stress and pressure. The key is to ensure an internally consistent approach, and integration and interpretation of all the data. By examining the available data and understanding the key issues previously encountered in drilling, testing or production, we can focus efforts on specific issues that will have the greatest impact on exploration and field development.

Learning Outcome

Delegates will at the end of the course be better able to:

  • Achieve understanding of geomechanical analysis
  • Understand wellbore stability analysis
  • Understand the causes of wellbore instability
  • Understand the principal stresses for effective planning
  • Assess stability or failure of system
  • Understand the term ‘’forces’’ and resistance to those forces
  • Understand drilling induced stress changes
  • Strategize for planning a stable wellbore
