... ABSTRACT Hydrate management has become a key topic in flow assurance due to the oil & gas production in cold environments (deep waters) and due to the high flow rates of water, especially in brownfields. Considering this, a hydrates formation and transport model is formulated and coupled...

... it is accurate and easy to implement for flow assurance engineers. 1. INTRODUCTION Sand management in multiphase flow operated pipelines is crucial in both onshore and offshore fields. As a matter of fact, solid particles can be produced from the reservoir and either transported or accumulated in the flow...
