ABSTRACT
Solid organic deposits (wax, asphaltene, and hydrates), along with scale and corrosion formation, pose formidable challenges for the offshore and onshore oil and gas industry. Despite taking preventive measures to avoid their formation, they may form in the oil and gas transportation facilities, albeit with some delay and challenge flow assurance. It is, therefore, necessary to understand fundamental principles governing their formation and develop mitigation methods to remove these deposits from the transportation facilities. It is important to precisely locate these blockages inside the flowlines and employ suitable removal methods. This chapter details the mechanism responsible for forming blockages in flowlines, followed by different mitigation methods for wax, asphaltene, hydrates, corrosion, and scales and their dosing rate for specific applications. The chapter concludes with details on the chemical inventory management for flow assurance.
