A technique facilitates monitoring and managing fatigue related a flexible conduit deployed from a surface vessel. Movements of the surface vessel may be measured to obtain vessel movement/position data. Based on this data, a flexible conduit bend profile may be determined via a computer-based data processing system. The flexible conduit bend profile may then be used to provide a flexible conduit fatigue profile for assessment of the flexible conduit in light of the environmental conditions. In some embodiments, the fatigue profile and assessment of the flexible conduit may be based on both functional loading and environmental loading.

Conduit fatigue management systems and methods

A system, method, and fluid analysis module are provided for the real-time analysis of multiphase fluids. The system generally comprises a sampling system for directing a fluid stream from a flow line to a fluid analysis module, a processor and communicator. The fluid analysis module comprises a sensor for measurement of at least one property of the fluid. The processor processes the measurement data from the sensor, and the communicator communicates the processed data to a central acquisition unit or computer.

Real-time measurement of reservoir fluid properties

A well for producing oil from an underground formation, comprises a vertical section extending from the surface to a depth below the oil-producing formation; a sidetrack or perforated interval (production zone) extending from the vertical section into the oil-producing formation; and a valve, located in the well, and operable to prevent flow of fluid from the vertical section into the production zone and a valve to prevent flow of fluid from the portion below the production zone into the production zone or into the vertical section above the production zone. A method of producing oil from the well comprises allowing oil and water to flow into the well via the production zone until the hydrostatic pressure of the oil and water in the well balances the formation pressure of the oil-producing formation such that further flow into the well ceases; allowing the oil and water in the vertical section of the well to separate under gravity so as to produce (i) a lower layer of water, at least part of which is located in the part of the vertical section below the oil-producing formation, and (ii) an upper layer of oil having its upper surface below the well surface and its lower surface above the production zone; forcing the separated oil and water back down the well and operating the valve such that substantially no fluid is forced into the production zone, an water is forced into the underground formation below the oil-producing formation; and allowing oil and water flow to recommence from the production zone.
