A packaged, fully instrumented water treatment and injection system for offshore use has been designed by the Aker Group of Oslo, Norway. The design also could be used on shore. Its standard Akar WIP 50 plant is rated at 50,000-bpd capacity at 3,000 psi injection pressure. Units may be arranged to achieve may treatment and injection capability. Systems use treated seawater, produced water, fresh water or ground water. Water supply is chlorinated and coarse-filtered at the system intake. Water carried through plastic, Eternit, or epoxy coated pipe will not need further treatment (deaeration for example) at the intake, Aker points out. Water injected into producing formations meets well-defined specifications. Before injection, water is filtered to reduce contaminants to an acceptable level. The standard degree of filtration is finer than 10 mu which helps to avoid blocking wells. Filters are simple in design and efficient in operation. Dependability and maintenance ease are design considerations. Filters have small external dimensions, are lightweight, and provide guaranteed degrees of filtration. A self-cleaning filter (50 mu size) can be put ahead of the fine filter to remove larger particles. Vacuum stripping is seen as the oxygen-removal method for the WIP 50.
