1.1 Overview

Production from wells is enhanced by ensuring the wells are designed optimally when drilled and completed. Particular focus is on assuring unrestricted flow through the lower completion of the wells for which sand control design, implementation, evaluation and subsequent management is key.

This 5-day “Fundamentals of Sand Control Design and Implementation” training course provides participants with the knowledge, understanding and tools required to design, implement and manage sand control completions. It starts by looking at the fundamental sand control considerations involved in completing a well and introduces the various sand control techniques commonly used across the industry, including standalone screens, gravel packs, high rate water packs and frac-packs.

The course then builds up the participants’ understanding of sand control completion and pumping operations through detailed discussion and practical exercises covering the principles, applications and design considerations of the various techniques.

Finally, it reviews post-job evaluation methods used in the confirmation of treatment success and investigation of failure as well as remedial sand control options, providing a full overview of sand control design, implementation and evaluation.

1.2 Objectives and Key Outcomes

The course is delivered interactively through engaging class lectures, presentations, practical exercises and projects which help participants to visualise downhole processes and cement their understanding of each technique’s advantages, limitations and application window for use in their upcoming completions A best in class commercial sand control software package (PackPro) is also used during the course to concretise theoretical learnings and practicalize designs and implementations.

By the end of the course, delegates will be able to:

  • Evaluate sand control requirements and design treatments for wells.
  • Visualise downhole processes, put into practice what they learn and gain practical sand control design and evaluation experience
  • Explore a variety of scenarios to identify the impact of design changes on the likelihood of treatment success.
  • Use the industry’s most advanced data analysis techniques to better understand complex downhole events and mechanisms
  • Apply the full sand control simulation, evaluation and optimisation workflow to continuously improve designs while minimizing risk.
