ABSTRACT:
Apparatus for separating particulate matter from a flowing fluid which, for example, may be sand entrained in a flowing stream of oil and gas, comprises an assembly including a plurality of small diameter tubular elements, the walls of which have a selected permeability to said fluid. The tubular elements are held with their axes parallel between a pair of headers by suitable tension means. The interior of the tubes are connected to at least one plenum and to a well tubing. When this assembly is inserted into a well producing oil and gas which carries sand, the sand will be deposited against the outer walls of the tubular elements since the grain diameters are greater than the size of the openings in the walls of the tubular elements. The fluid flows through the openings in the wall of the tubular element, into the plenum and then through the well tubing to the surface of the well. By using suitable headers at each end, a plurality of these assemblies can be connected in series. This apparatus is equally applicable to the filtering of any type of particulate matter from any type of fluid.
