Advanced Formation Pressure Evaluation

16th March 2015


The workshop is designed to present current state of the art approaches to formation pressure and earth stress evaluation up to and including HTHP wells. Subsurface non-productive time (NPT) currently accounts for some 10% of well costs. This course will provide the key tools to help to predict, evaluate and mitigate subsurface risks to enable wells to be drilled much more cost effectively. As well as presentations a number of class exercises and case studies will be used to enhance learnings. Tim will pass on hints and tips from his long experience working with formation pressures.

Benefits Of Attending

  • Evaluate earth stresses and their relationship to pore and fracture pressures
  • Recognise wellbore instability caused by anisotropic stress
  • Calculate overburden pressures and their importance in pore and fracture pressure calculations
  • Calculate fracture pressures and evaluate LOTs and FITs
  • Learn the importance of recognising pore pressure generation mechanisms
  • Examine the controls on pore pressure distribution post generation – understanding the centroid principle and hydrodynamics
  • Execute pore pressure prediction using seismic and basin modelling
  • Understand quantitative pore pressure calculation methods
  • Explore the interpretation of key pore pressure and earth stress indicators – caving, gas, hole conditions etc
  • Use and interpret direct pressure measurements
  • HTHP and deepwater wells from the geologist’s perspective
  • Mitigation techniques for risks in well planning and execution of HTHP wells
  • Use of managed pressure drilling (MPD) in HTHP

Who Should Attend

The case is aimed at professionals involved in the planning and execution of wells where formation pressures are an issue. As this is an advanced course attendees will be assumed to have a working knowledge of rigs and drilling activities.

  • Operations geologists
  • Wellsite geologists
  • Drilling engineers
  • Regional geologists
  • Senior mudloggers
