Bubble Pump Utilization for Vertical Flow Line Liquid Unloading |
摘要 |
A method, including: performing dual-side depressurization on a hydrate blockage in a subsea flow line, wherein dual-side depressurization includes, reducing pressure on a topside of the hydrate blockage in the subsea flow line by removing liquid from within a subsea riser with a bubble pump that has a first end in fluid communication with the liquid within the subsea riser, reducing pressure on a backside of the hydrate blockage, and concurrently controlling the reduction in pressure on the topside of the hydrate blockage and the backside of the hydrate blockage. |
