Flow Assurance Workshop
Introduction
To satisfy the world’s ever increasing demand for energy, Oil and Gas companies continue to develop and extract reserves in more and more hostile environments from deep water to the Arctic;
As conventional oil reserves decline, companies are developing unconventional fields with
complex fluid properties; All these factors mean that flow assurance plays an increasingly important role in the oil
and gas industry and employers are frequently seeking skilled engineers in this field; This one-week introductory course covers all aspect of flow assurance for the oil and gas
industry, but with relevance to all industries with fluid flow related issues such as nuclear and process industries.
Objectives
On successful completion of the module, the participants will be able to:-
Gain a systematic understanding of the concept of flow assurance; Apply competently the fundamental principles of fluid mechanics, heat and mass transfer
to analyse typical flow assurance systems; and Design for basic flow assurance and operability
