Here's What You Will Learn:
Here's What You Will Receive:
 
  • How to assess when wellbore stability, sand production, or lost circulation will be a problem
  • Basic techniques to obtain and apply earth stress and rock strength data
  • The effects of pore pressures, mud properties and time on wellbore stability
