  • Method of filtering a wellbore fluid
    Patent number: 10815760
    Abstract: A method of filtering a wellbore fluid can include receiving a wellbore fluid in a chamber. The chamber can be defined by an inner surface of a casing string that is positioned downhole in a wellbore. The method can further include filtering debris particles from the wellbore fluid by a filter assembly positioned within an inner region of the casing string. The filter assembly may include a plurality of slots and the filter assembly may be rotated by the wellbore fluid passing through the plurality of slots in the filter assembly.
    Type: Grant

  • Filter assembly
    Patent number: 10233731
    Abstract: An apparatus may include a slotted filter that is generally circular in shape and positionable within a casing string. The slotted filter may include multiple filter chambers. Each of the multiple filter chambers may include a rear wall; side walls that intersect the rear wall; slots in the rear wall and the side walls; a bottom surface; and an open end positionable proximate to a centrifuge in the casing string for receiving a fluid containing debris particles collected by the centrifuge.

  • Centrifugal particle accumulator and filter
    Patent number: 10233730
    Abstract: An assembly may include a diverter extending inwardly from a casing string and extending along a length of the casing string. The assembly may also include a cavity defined by the diverter and the casing string. The cavity may be for receiving debris particles accumulated by a centrifuge positioned proximate to the diverter. The assembly may also include a valve extending between an inner surface of the casing string and an outer surface of the casing string, the valve may be in fluid communication with the cavity.

  • Centrifugal particle accumulator
    Patent number: 10125579
    Abstract: An apparatus can include a first curved blade for use in a centrifuge. The centrifuge can be for collecting debris particles in a fluid flowing through the centrifuge. The first curved blade can include a plurality of eccentric slots. The first curved blade can include a groove positioned at an outer edge of the curved blade. The first curved blade can also include a first mating element and a second mating element. The first and second mating elements can be for coupling the first curved blade to a second curved blade about a central axis.
