Abstract

Oil processing apparatus for the treatment of a mixture containing oil and other constituents. The apparatus comprises two types of separators arranged to co-operate together, the first separator (22) being of the type capable of handling a mixture containing a relatively high percentage of oil and the second separator (26) being of the type capable of handling mixtures containing a relatively low percentage of oil so that substantially full separation of the oil and other components can be achieved. There is also provided a system for recovering oil from a subterranean reservoir wherein apparatus which may be of the type described above is at least partially located underground.
