Ni-Fe Nanomaterial: Ameliorating Flow Assurance

摘要

Thermal factor deals with the temperature of reservoir, producing fluid temperature profile and heat transfer through the conduit. Parabolic temperature profile of producing fluids in production tubing’s favour deposition within the conduit thus resisting flow rate and causing additional pressure drop. Passive insulation provides loss in maintenance of fluid temperature and in deepwater and ultra-deep water applications, this approach would be ineffective as the riser static head is big and it will prevent the pipeline pressure to reduce below the hydrate forming pressure. For any producing system to be economical and successful, Flow assurance is a major challenge to be dealt with while producing a petroleum reservoir. Commonly used methods are chemical injection and direct electric heating which encounter many challenges in assurance. Thermal factor is the major contributing impetus for mitigating problems related to the flow of the hydrocarbons from the reservoir. The thermal factor is an effective and required solution. Active heating provides the capability to monitor and control the fluid temperature to be utilized for proposed technique. However, development of thermal management strategies applied for the design of subsea production systems is critical for prevention of deposition, thus leading to issues pertaining to flow assurance. Therefore, this paper introduces Ni-Fe Nanomaterial as a promising approach to solve flow assurance problems. The basis of the Ni-Fe nanomaterial seen from hysteresis and relaxation losses under induced magnetic field which generates a sufficient heating environment. The attractive aspect of this technique is the low dosage requirements and its innocuous and environmentally safe nature.
