Wax prevention and remediation in subsea pipelines and flowlines ///

Paraffin wax deposition costs the oil industry billions of dollars worldwide for prevention and remediation. Paraffin precipitation and deposition in crude oil transport flowlines and pipelines is an increasing challenge for the development of deepwater subsea hydrocarbon reservoirs. If sufficiently deposited over time, wax can partially or totally block oil production to uneconomical levels requiring shutdowns and/or various remediation treatments. The increasing exploitation of deepwater fields makes it critical to understand the mechanism of wax depositions and how to prevent and remediate wax deposits in deepwater production operations.
