Course Description

This course reviews fundamental sand control concepts and goes on to detail the mechanisms, applications and challenges of the various open hole gravel pack treatment types with practical examples for each. It uses the PackPro software to demonstrate the impact of changing both surface pumping parameters and downhole completion hardware on the success of gravel pack treatments. The course culminates in a practical project requiring students to apply what they have learned by selecting, designing and presenting the most appropriate sand control completion for a number of case study wells.


Agenda

Day 1 – Review of Sand Control Basics

  • Sand Control Introduction – Review the basics of geo-mechanics and sand production, discussing the importance of sand control and the conditions under which it may be required.
  • Sand Control Techniques and Selection – Review the various sand control techniques used across the industry along with their respective applications, advantages and challenges.
  • Surface Equipment and Downhole Tools – Review the surface equipment and downhole tools used to execute sand control treatments, including high pressure pumps and service tools.
  • Screen and Gravel Selection – Discuss the guidelines used in selecting the most appropriate screen and gravel (types and sizes) for a well.
  • Pumping Fluids Systems – Discuss the various carrier fluid systems used in sand control treatments including Newtonian, VES and polymer.
  • Well Preparation for Sand Control – Discuss the various well considerations while installing the sand control completion including reservoir drilling fluids (RDFs), wellbore cleanout and fluid loss control.

Day 2 – Alpha/Beta, Alpha/Alpha and RPGP

  • Overview and Packing Mechanisms – Discuss the basic principles and packing mechanisms of alpha/beta, alpha/alpha and reverse-port gravel packing techniques.
