Abstract: A downhole tool for removing debris from fluid flowing through the downhole tool comprises a screen member and wiper member, the wiper member having at least one window disposed through the inner and outer wall surfaces of the wiper member. Either the screen member or the wiper member is rotatable such that rotation of the screen member or the wiper member causes debris disposed on the outer wall surface of the screen member to fall-off the screen member. At least one directional port disposed at either the upper end of the screen member or the upper end of the wiper member causes rotation of the screen member or wiper member when fluid flows through the downhole tool.

Abstract: A downhole tool for removing debris from fluid flowing through the downhole tool comprises a screen member in sliding engagement with an inner wall surface of the tool. As the screen member becomes blocked, it moves from a first or initial position to a second or actuated position which causes a pressure change detectable at the surface of the wellbore. The pressure change causes the debris blocking fluid flow through the screen member to fall off the screen member thereby allowing an increase in fluid flow through the screen member. As a result, the screen member returns to its initial position and fluid again flows through the screen member for capturing by the screen member.

Abstract: A downhole tool for removing debris from a wellbore comprises a mandrel and a shroud disposed around a portion of the mandrel. The mandrel includes at least one mandrel port in fluid communication with a mandrel bore. The shroud includes a cavity and a shroud port. Debris laden fluid is pulled into the shroud cavity by flowing fluid through the mandrel bore, out the mandrel port, into the shroud cavity, and through the shroud port. The debris-laden fluid is pulled into the shroud cavity due to a pressure differential created by the flow of the fluid through the mandrel port and out of the shroud port. As the debris laden fluid flows into the shroud cavity, the debris is captured within the tool.

Abstract: Anchoring systems for disposition in wellbores and tubular devices comprise a tubular member defined by two or more radially expandable slip members. The upper ends of the slip members are shaped such that when the slip members are in their respective run-in positions and in their respective set positions, a portion of an upper end of one slip member overlaps a portion of an upper end of another slip member so that the longitudinal space between each slip member that is created when the slip members are in their set position are blocked by the upper end of at least one of the slip members. Thus, in their set position, the upper end of at least one of the slip members provides a back-up to a sealing element that can be disposed adjacent to and in contact with the upper ends of the slip members when in their set positions.
