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.
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.
