Installation and method for the offshore exploitation of small fields

摘要

System for optimizing the development of small oil deposit comprising a main platform, a floating structure including pumping means, the system being positioned close to at least one production wellhead, mechanism for transferring the effluents from said well towards the floating structure and from the floating structure to the main platform. The system comprises a device for taking a sample of a fluid from said effluents and at least one device for injecting said fluid at the level of the wellhead. PPThe method comprises a stage of transfer of the effluents of a deposit towards a floating structure located close to the deposit, taking a sample of fluid from the effluents, reinjecting this sample of fluid at the level of an immersed wellhead and transferring the effluents towards the main platform.
