Paper presented at the PSIG Annual Meeting, May 10–13, 2022
Paper Number: PSIG-2201
... Abstract Gas hydrates are a major flow assurance problem in the oil & gas industry. If not treated well, they pose a major threat to pipeline failure. In this work, a simple statistical correlation is developed for the prediction of gas hydrate formation temperature. For this, initially...

... assurance problems such as increased corrosion rates, increased pressure drop in pipes and pigging blockage. Thus, the prediction of sand transport velocities is of great importance for flow assurance in petroleum as well as mining industries. The processes in these applications must be designed...
