Abstract: A filter includes a cylindrical pleated filter element having a longitudinal axis, an inner and outer periphery, first and second end surfaces, and a plurality of longitudinal pleats. First and second end elements are sealingly arranged with the first and second end surfaces, wherein at least one of the end elements is an open end element. The filter element is a pleated composite that includes a filter medium, an upstream drainage medium and a downstream drainage medium. Each pleat includes a crown, a root, and a pair of legs. The legs of each pleat are joined to one another at the crown of the pleat and are joined to the legs of adjacent pleats at the root of the pleat. Each pleat leg abuts an adjacent pleat leg along the inner periphery of the filter element and the pleats extend from the inner periphery in a curved, an arcuate, an angled, or a straight nonradial direction to the outer periphery. The height of each pleat, measured in a direction along the legs and extending from the inner periphery at the root of the filter element to the outer periphery at the crown of the filter element is greater than (D-d)/2 and less than (D.sup.2 -d.sup.2)/[4(d+2t)], where D and d are the outer diameter and the inner diameter of the filter element and t is the thickness of each leg.

Abstract: A particle control screen assembly for a perforated pipe used in a well, a sand filter system, and methods of making same are provided. The screen assembly includes a woven mesh filter media disposed about the perforated pipe, and a protective wrapper disposed about the filter media. The protective wrapper comprises an outer perforated layer and an inner layer that is disposed between the outer layer and the filter media. A surface of the inner layer that faces the outer perforated layer has a non-smooth contour, with this surface of the inner layer having portions in direct contact with an inner surface of the outer layer. The inner layer is provided with apertures that are disposed in such a way that fluid cannot flow from the outer surface of the outer perforated layer directly radially both through holes of the outer layer and through the apertures of the inner layer.

Abstract: A method of manufacture of a radial-flow filter particularly suitable for use as an input filter in a subterranean fluid (oil, gas, water) well starts with a length L of multi-perforate pipe, which may be an integral part of the production tubing of the well. The pipe is mounted in an engine lathe with the perforated length L between the headstock and the tailstock of the lathe. With the pipe rotating, a strip of metal wool, preferably stainless steel wool, is wrapped around the pipe in repeated, overlapping helical layers each aligned at an acute angle X to the pipe axis, with adjacent layers angularly displaced by an angle 2X. The completed filter may have a tubular wire mesh around the pipe, between the pipe and the innermost layer of steel wool, and a multi-perforate sheath over the outermost layer of wool.

Abstract: The invention is a spin-on type filter with a reclaimed permanent filter casing and permanent filtering mediums that are washable and reusable. There are three distinct progressive filtering systems that function simultaneously, but separately within one filter housing; one is the full flow filtering at 10 micron capability while the other is in its by-pass fine filtering mode at 1 to 3 micron filtering capability. In addition, a safety full flow filter can be activated to filter the return oil while the main fill flow medium is fouled. Each system can be implemented with multi mediums. The main body of the filter, which comprises the filter head and the mediums, can be separated easily for servicing from its casing which is designed to attach to the engine. Fine stainless steel cloths are being utilized as filtering mediums which can last the life of an engine. Further more, magnetic pieces are utilized to trap suspending metal filings in oil flow. The design of the main filter body as such is that any used conventional filter canister can be simply adopted to it or a new filter canister casing can be utilized whichever is the advantage at the time of installation and of in production.

Abstract: A filter element has a support member with a support tube which can abut a filter mat and which is provided with apertures for the passage of a filtered medium. The apertures are formed by the axial spaces between individual rings of the support member. The rings are supported by support walls dividing the interior of the support tube into individual chambers. Since the support member is rendered compression-stiff, it exclusively supports the filter mat when the medium flows through. The respective support wall is directly connected to the rings. Each ring with its closed annular shape surrounds the support walls on the exterior. The filtration capacity of filter elements can be improved and the weight and cost simultaneously reduced owing to the highly stable and compression-stiff support member.

Abstract: A damage-resistant filter for use in subterranean wells has at least one layer of a filter medium, such as a sintered supported porous membrane, coaxially disposed about a perforated support member. The filter may also include a drainage layer disposed between the inner support member and the filter medium, and a protective covering, such as a perforated cage, surrounding the filter medium. The filter is particularly suitable for removal of sand and other particulates from fluids produced in a well.
