Abstract: The present disclosure is directed to a filtering assembly and a method of manufacturing a filtering assembly. The filtering assembly may increases an effective screening area. Specifically, embodiments disclosed herein include a screen housing having two sidewalls and two end walls, defining a perimeter with a length and a width. The screen housing also includes a top face and a bottom face. A plurality of screen segments may be positioned on the top face of the screen housing, such that the plurality of screen segments on the top face provide a screening surface area less than a total surface area of the top face.

Abstract: An apparatus having a screen frame with a first screening surface and multiple openings is disclosed. The openings can be bounded by at least one mating surface. One or more screen filter unit having a second screening surface can be disposed in one of the openings of the screen frame. The one or more screen filter unit can have one or more sealing surface that can be coupled to the at least one mating surface of the screen frame.

Abstract: A valve assembly for use in a wellbore of an oil, gas or water well, having a valve seat to seat a valve closure member such as a ball, and a control member that is adapted to cycle the valve assembly between first and second configurations of the valve assembly when the ball is seated on the seat. The valve assembly may be adapted to return the valve assembly to the first configuration when the valve closure member is seated on the seat, and may repeatedly, continuously and/or sequentially cycle from first to second configurations and back to first configuration to open and close an outlet port while the same valve member is seated on the seat. The valve seat may comprise first and second seat members and retain the ball in a cleft between the first and second seat members.

Abstract: A filter device housed within a body component. The filter device can include an outer filter and an inner filter positioned coaxially within the outer filter. The outer and inner filters may be composed of a material having mesh, slots, holes, or any other openings being of a sufficient size and shape to restrict passage of items of a predetermined size or larger. Formed between the inner and outer filters is a first annular space into which fluid that is provided down the drill string may enter. The filter device may also include a valve within the internal bore which regulates passage of wellbore fluid provided to the drill string, or for a wireline or slickline, to pass through the filter device in order to access other components of the drill string downhole from the filter device.

Abstract: A method and/or a system filters particles using a screen with modular segments installed into a frame. The frame has a perimeter structure and an orthogonal array of support members. The segments have a segment perimeter frame, an orthogonal array of ribs and a mesh stretched across the segment. When the mesh of the segments is damaged, the damaged segment is removed from the frame and a replacement segment is installed.

Abstract: A flow diverter including a bypass element to divert at least a first portion of drilling fluid from a drill string to the borehole annulus. The first portion of fluid, or bypass flow, may be provided to the borehole annulus to clear cuttings generated by a drill bit of a BHA. The remaining fluid flow, or BHA flow, may be expelled through the bottom of the BHA. The fluid discharged through the BHA may enter the annulus and flow upward with the fluid flow diverted through the flow diverter to aid in clearing cuttings. The flow diverter also includes a choke housing disposed concentrically within a drill collar and containing a plurality of chokes to regulate bypass flow. An actuation system may be coupled to the flow diverter to control opening/closing of the chokes and to measure flow rate of the first portion of fluid and/or the remaining fluid.
