Paper presented at the Offshore Technology Conference, May 4–7, 2020
Paper Number: OTC-30857-MS
... Abstract Hydrates are crystalline water compounds that may form in deepsea pipelines and have the ability to quickly and efficiently plug flow. Given this issue, gas hydrate formation tests have been conducted and reported in a number of published articles. However, most published data has...
