Geomechanics for Drillers

GEOM-EN-P

Who should attend?

  • This training course aims to ensure the understanding of geomechanics-related drilling problems such as wellbore stability and fluid losses, and to be aware of the techniques used in the petroleum industry to mitigate these phenomena.
Public :
  • Engineers and supervisors involved in drilling operations.

Level :Skilled

Prerequisite :
  • Basic drilling knowledge as well basic geological ones.

Course Content

  • INTRODUCTION TO GEOMECHANICS IN THE PETROLEUM INDUSTRY - Duration : 1.5 hours

      • Review of all the applications of geomechanics in the reservoir and drilling fields illustrated with real cases.
  • THEORETICAL BASES USEFUL FOR DRILLING APPLICATIONS - Duration : 12 hours

      • Stresses, deformations, elasticity.
      • Connection between stress, pressure and temperature.
      • Rock tensile failure.
      • Rock shearing failure.
      • Laboratory measurements of tensile and rupture properties.
      • Geomechanical model of wells (formation pressure, stresses and mechanical properties) and calibration from laboratory measurements and data and well tests.
      • Different types of pressure tests in drilling, in particular the leak-off test.
  • STRESSES & RUPTURE MECHANISMS AROUND THE WELL - Duration : 12 hours

      • Radial, axial and tangential stresses.
      • Shearing failure conditions and calculation of the minimum mud weight.
      • Conditions of tensile failure and fracture propagation and calculation of the maximum mud weight.
      • Impact of the well path.
      • Impact of reservoir production of infill drilling in already producing reservoirs.
  • APPLICATION - Duration : 4.5 hours

      • Exercise based on one or several real cases gathering the major issues of reservoir geomechanics.
      • Knowledge assessment.

Learning Objectives

  • Attendees will be able to implement the following skills:
  • acquire the basic geomechanical knowledge useful for drilling operations,
  • diagnose the mechanisms of wellbore instability and fluid losses including already producing fields,
  • identify the drilling-related geomechanical parameters as well as the means to measure or assess them from well data and laboratory measurements.

Ways & Means

  • Application exercises adapted to drilling situations.

Learning assessment

  • Acquired knowledge will be assessed through studies based on real cases. In each study, participants will have to analyze the situation to provide a diagnosis and possible solutions.
