The operation of crude oil pipeline: Examination of wax thickness

Abstract

Solid and wax precipitation during production, transportation, and storage of petroleum fluids is a common problem faced by the oil industry throughout the world. Continuous wax deposition is a critical issue for offshore transport pipeline and for the oil and gas industry. Significant amount of effort and capital are typically spent annually by the Oil & Gas companies for the prevention and removal of wax in production and transportation lines. This study examines a new technology to monitor wax deposition thickness in sub-sea pipelines. The wax thickness predictions from the wax thermal sensing method is expected to be promising compared with conventional measurement techniques. It is expected that this sensing method can support the operators of Oil & Gas companies to predict accurately wax deposition which enables operators to adjust operation quickly to prevent a complete clogging of pipelines.
