This is a Joint Industry Project (JIP). The purpose of this project is to develop a model to predict the rate of hydrate plug decomposition; to measure the mobility of hydrate plugs with/without kinetic inhibitors; and to characterize the morphology of gas hydrates.
Complete. Depressurization (venting) and chemical injection were investigated as methods to remove hydrate blockage from subsea gas or gas condensate pipelines. A mathematical model was developed for the plug decompression process. The model was experimentally validated. Hydrate plug decomposition by chemical injection can be an effective process for blockage removal, when decompression is not possible.
