The detection of blockage location in a deepwater flowline running from a subsea well to the host platform is an integral part of deepwater subsea flow assurance area. As E&P is moving into greater water depths, flow assurance in subsea flowlines is increasingly becoming important. Deep water production fields are facing even new challenges nowadays. The major problem with deep water installations is the deposition of solids like hydrates, waxes, asphaltenes and scale in the flowlines. These depositions grow slowly and reduce the flow rate of oil and gas steadily. Eventually after few days or...
