2.1 Overview

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

This 5-day ADVANCED Sand Control Design and Optimisation Training course provides participants with the knowledge, understanding and tools required to design, implement and manage sand control completions.

The course discusses the principles, application scenarios and design considerations of the various sand control techniques commonly used across the industry, including standalone screens, gravel packs, high rate water packs and frac-packs. It follows and extends the “Fundamentals of Sand control completions” course and requires attendees to have some understanding of sand control operations including the fundamental concepts of the different sand control techniques.

The course is designed for drilling and production personnel who are looking to gain a better understanding of sand control operations, including the ability to select the optimum sand control technique for their wells. It also covers remedial sand control options and gravel pack evaluation, culminating in a practical project which requires attendees to apply what they have learned by selecting and designing the most appropriate sand control technique for a case study well.

2.2 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 sand control software package 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 treatment options for wells.
  • Understand the operational steps involved in installing a sand control completion.
  • 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.
  • Learn about remedial sand control options and considerations
  • 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 and NPT.
