Flow Assurance

Course Description

This course is aimed at leaders, managers and engineers working on oil and gas field projects and operations who wish to develop their understanding of flow and fluid issues between sand face and separator, and of how to manage those issues. Particular emphasis will be given to the interrelatedness of flow assurance with many other engineering disciplines and with key project and operational decisions.

The course assumes basic engineering education and experience. It will build on fundamental principles to develop an understanding of what flow assurance is, and how to successfully address flow assurance issues in oil and gas field development projects and operations.

 

Course Objectives

  • To describe fluid-related issues, how to obtain appropriate fluid samples to assess risk of those issues, and ways to manage the issues.
  • To describe flow-related issues, and ways to manage the issues.
  • To provide an understanding of what key project decisions need flow assurance input.
  • To investigate methods and software to assist in flow assurance engineering.
  • To discuss how to get flow assurance engineering work done efficiently and effectively.
  • To identify interfaces with related engineering disciplines, and to describe the necessary information exchange with flow assurance.
  • To provide insights into how to assess and deal with operational flow assurance issues.
  • To illustrate with field examples.
  • To have attendees participate in case studies to reinforce key learnings.

 

Who Should Attend

  • Oil and gas field development project managers, and operations managers, of fields with long flow lines between wellheads and processing facilities. The course will give them an overview of the potential complexity of the flow and fluid issues and how these can affect decisions in many related areas.
  • Aspiring flow assurance engineers and production chemists, particularly with a chemical engineering, process engineering or petroleum engineering background. The course will give them an appreciation of the breadth of flow assurance and how to ensure that flow and fluid issues are addressed safely and cost effectively.
  • Engineers in related disciplines (particularly subsurface, completions, petroleum, subsea, process, materials, static mechanical). The course will give them an understanding of the issues for which they need to work alongside flow assurance engineers.
  • University chemical and petroleum engineering lecturers and researchers who wish to understand one application of their discipline.
