... ABSTRACT This paper considers the huge changes in the oil industry's understanding of multiphase flow over more than 4 decades, and the application of that understanding into the engineering discipline of flow assurance that has developed in the same timeframe. Initial test facilities were...

... ABSTRACT Gas hydrate formation in oil and gas pipelines may cause flow assurance problems, especially in deep water subsea tiebacks. Agglomeration of hydrates may form plugs, thereby halting production. In the last decades, the hydrate control philosophy has shift from "hydrate avoidance...

... 4% hydrate fraction was found for a 1 -ID pipe (14). If those increases are high enough to make the hydrate dispersion to change from homogeneous to heterogeneous, or to make the particles to settle in the pipe, then a pipe obstruction might occur quite quickly, becoming a flow assurance threat...

... during oil transportation, paraffin molecules reach the wall or the interface of the oil and deposit. They crystallize and become a part of the deposit. This phenomenon is known as paraffin deposition which is one of the key flow assurance issues in oil industry. In this study South Pelto oil, and Garden...

... The formation and accumulation of natural gas hydrates in deep subsea pipelines is one of the most challenging flow assurance problems. Typical high pressure/low temperature operation conditions in deep subsea facilities promote rapid formation of gas hydrates. Recent observations in flowloop experiments in gas...

.... Hydrates are considered as one of the important flow assurance problems, if not the most, to be managed in Multiphase Production. Professor Sloan will share his knowledge and wisdom with a talk titled "Developing a comprehensive understanding and model of hydrate in multiphase flow: From laboratory...
