Geomechanics for Petrophysicists

Geomechanical modelling requires a multi-disciplinary approach with petrophysical data sitting firmly at its core. Geomechanics has a role in drilling, well completion and production.

  • Wellbore instability problems are a significant contributory factor in non-productive time
  • Sand production is a major issue during oil and gas production from reservoirs with lower rock strength
  • Reservoir compaction and subsidence can present many challenges for reservoir management
  • Knowing the risk of fracturing is fundamental for containment.

Understanding near wellbore geomechanics is essential in diagnosing and ensuring formation and well integrity, particularly as operators look to develop more challenging reservoirs.

Petrophysics is fundamental to geomechanical modelling as log and core data are used to derive the intrinsic rock properties, understand the failure behaviour and support development of the stress model. The validity of the model relies on robust quality assured data. By learning the application of petrophysics data in geomechanical modelling, consistent fit-for-purpose data can be achieved. This short course is designed for petrophysicists, drillers, production engineers and geoscientists who wish to expand their knowledge in geomechanics and how it impacts on well construction and completion decisions.

Top Learning Objectives

  • Explore why geomechanics is important in field development

  • Learn how to build a stress model from logs and field data
  • Determine stress direction and understand the benefits of knowing how stresses are orientated
  • Study how pore pressure is estimated and calibrated?
  • Understand what controls the risk of sand failure
