摘要： The invention relates to the reduction and prevention of biofouling in facilities utilizing water, e.g. sea water, carrying biological organisms, without causing corrosion, chemical reaction or other detrimental action from the additive or environmental discharge problems. Such operations include, for example, desalinization plants, power plants, oilfield water injection facilities and shipboard or ocean platform fire water systems. For example, in the desalinization plant of Fig. 1, the biofouling reduction method and apparatus for this invention has a source of oxidizing agent (e.g., chlorine ions or ozone), a source of copper ions and a dosing chamber (25) for delivery of relatively low dosage levels of oxidizing agents and at appropriate times copper ions to form a treatment additive. Flow connectors (29) connect the dosing chamber (25) to various points along the piping in the desalinization plant. A controller (31) controls the operation of the dosing chamber and valves (33) along the flow connectors (29) to operate in a sequential target dosing mode to deliver treatment additive of predetermined composition to selected points along the piping at predetermined times and in predetermined concentrations.

摘要： Downhole apparatus (13) for separation of oil from oily water or water from oil having an internal chamber (20) continuously flooded with production fluids from a well, one or more hydrocyclonic separators (2) for separating the production fluid into a stream enriched in oil and a stream depleted in oil. The clearance required between the apparatus (13) and the well casing (17) being the minimum required for running the apparatus into the casing (17), maximizing the size of the separator(s) and improving capacity. A range of artificial lift devices is included to bring the oil enriched stream to the surface if the natural pressure of the reservoir is insufficient. Substantial axial overlap of multiple separators is provided for better compactness and capacity of the apparatus. Pipes (5) from separator overflow outlets connect to a common overflow manifold (7), and pipes (6) from the separator underflow outlets connect to a common underflow manifold (8). Where the space available for pipes (5, 6) and manifolds (7, 8) is limited adjacent to the separators the manifolds (7, 8) may be formed with a non-circular cross section having substantially the same cross-sectional area as adjacent portions of the manifold.

摘要： A method of separating oil, water and sand in a production fluid. The production fluid is fed through a downhole liquid/liquid hydrocyclone (9). An oil enriched stream from the hydrocyclone (9) is pumped to the surface, while an oil depleted stream is fed to a downhole solid/liquid hydrocyclone (12). Here, the bulk of the solids are separated from the water, so that water which is substantially free of solids can be transported to a downhole disposal site (14).
