摘要： 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.

摘要： Once an oil well has been drilled and is producing, it is desirable to monitor the rate at which oil or gas is being delivered. It is particularly useful to know when there is a change in a fluid's output rate, for that can indicate problems with the well. This monitoring is known as “production logging”. Prior to the introduction of horizontal well drilling, most wells were either vertical or only slightly deviated. However, many present-day wells have long horizontal or nearly-horizontal portions, and the techniques used to measure flow in vertical wells are not applicable to horizontal wells. Moreover, any flow rate measurement technique to be used downhole should take account not only of the several sorts of “lined” wells but also the “barefoot” ones. The invention seeks to satisfy this need for a technique that can be employed with all these sorts of completed well by utilizing a pair of correlated spaced sensors (that can detect “directly” the difference between gas and liquid (oil and/or water), which sensor pair is carried on a logging tool positioned within the borehole itself such that the individual sensors are disposed so as to be actually in the path of any gas bubbles likely to be in the fluid. The correlated output of the sensor pair allows a determination of the gas flow velocity, and if at the same time measurements are taken that provides an indication of the hold-up of the gas bubbles there may by calculation be determined the flow rate both of the gas and of the fluid.

摘要： 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.
