Introduction

In the development of a hydrocarbon reservoir, many wells are drilled and required to be completed, to allow the structure to be depleted. However, the drilling and completion operations are crucial to the long-term viability of the wells in meeting the specified objectives.

The design and completion of both production and injection wells are required to satisfy several objectives including:

• Provision of optimum production/injection performance
• Ensure safety
• Maximize the integrity and reliability of the completion over the envisaged life of the completed well
• Minimize the total costs per unit volume of fluid produced or injected, i.e.
• Minimize the costs of initial completion, maintaining production and remedial measures

This training on Well Completion Design will feature:

• The main functions of completion
• Developing a high-level completion strategy for wells in a variety of situations
• Select tubing, packers, and completion flow control equipment

Understand different sand control techniques and their application

Objective

By the end of this course, participants will be able to:

• Evaluate for a given reservoir scenario the bottom hole completion options and make a recommendation based on well integrity and reservoir management requirements
• Identify, evaluate and recommend functional capability of completion strings for a variety of situations
• Describe the purpose and generic operating principles for major completion equipment components
• Identify limitation of well completion schematically designs and potential failure mechanisms / operational problems with equipment
• Assess well safety requirements and capabilities inherent in well design
• Describe the integration of the various stages of completing a well
• List and flow chart a general procedure to run a completion string
• Describe the requirements to pressure test and retain well control throughout the completion process
• Define the need for full and accurate reporting and records to be kept

Methodology

The training course will be highly participatory and the course leader will present, guide and facilitate learning, using a range of methods including formal presentation, discussions, sector-specific case studies and exercises.  Above all, the course leader will make extensive use of real-life case examples in which he has been personally involved. You will also be encouraged to raise your own questions and to share in the development of the right answers using your own analysis and experiences.  Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course.

• 30% Lectures
• 30% Workshops and work presentation
• 20% Case studies & Practical Exercises
• 10% Role Play
• 10% Videos, Software or Simulators (as applicable) & General Discussions
