  • Patent number: 9254454
    Abstract: A method of assembling a sand screen assembly includes the steps of providing inner and outer shrouds having radial protrusions, such as ribs, louvers, splines, etc., that are radially unaligned during a first assembly step thereby providing clearance for positioning of a filter layer between the shrouds. The outer or inner shroud is then rotated until the protrusions are aligned and the clearance between the shrouds and filter layer is eliminated to provide a tight fit between the layers.

  • Patent number: 9187987
    Abstract: A system and methodology utilizes a technique for filtering sand; distributing a flow of fluid; e.g. distributing an inflow of gas or condensate; and limiting the potential for erosion of completion components in a wellbore. The technique may be useful in production applications, but the technique also can be used in fluid injection applications, e.g. gas injection applications. The technique employs a base pipe and a sand screen surrounding the base pipe. The base pipe comprises a plurality of flow restriction openings of reduced size and deployed in a selected pattern along the base pipe. The size and arrangement of the flow restriction openings reduces the peak flux of radial fluid flow through the sand screen to a rate less than a sand screen erosion rate.

The separation assembly can include ether one, two, or more segments or stages of varying lengths depending upon the individual application. The assembly is installed into the tubing string or delivery conduit of a well producing hydrocarbons. One stage can consist of a velocity chamber whereby separation of particulates occurs by increasing the downward velocity of particulates and reducing the upward velocity of hydrocarbons thereby allowing the particulates to “fall-out” into a lower chamber where the particulates are captured. Another stage can consist of a filter whereby particulates are captured in a chamber that can consist of filtering materials such as gravel, rock, sand, wood, or manmade materials. Each of the stages can be employed individually or in combination.

  • Publication number: 20130092391
    Abstract: A system and methodology utilizes a technique for filtering sand; distributing a flow of fluid; e.g. distributing an inflow of gas or condensate; and limiting the potential for erosion of completion components in a wellbore. The technique may be useful in production applications, but the technique also can be used in fluid injection applications, e.g. gas injection applications. The technique employs a base pipe and a sand screen surrounding the base pipe. The base pipe comprises a plurality of flow restriction openings of reduced size and deployed in a selected pattern along the base pipe. The size and arrangement of the flow restriction openings reduces the peak flux of radial fluid flow through the sand screen to a rate less than a sand screen erosion rate.

    Abstract: A method and a system for segmental flow control in an oil-gas well are disclosed. The oil-gas well includes a first annular space (111) and a second annular space (103). The first annular space (111) is formed with the space between the borehole wall (101) of the oil-gas well and a perforated tube (102) which is in the oil-gas well and extends along an axial direction of the oil-gas well; The second annular space(103) which is formed with the space between the perforated tube(102) and a flow-control filter string (105) which is in the perforated tube(102) and extends along the axial direction of the oil-gas well. The method includes filling anti-channeling isolating particles (109) in the first annular space (111) and the second annular space (103) to enable fluid to flow in the first annular space (111) and the second annular space (103) filled with the anti-channeling isolating particles (109) in the manner of seepage.

  • Publication number: 20120292047
    Abstract: Disclosed is a downhole well filter (800) and method of use in a tubing string with a power head (704) for creating reverse flow. The filter assembly includes an inner pipe (820) into which fluid flow is directed. The inner pipe is positioned within a cylindrical screen member (830). The well fluid flows through the screen member and debris from the fluid is deposited in the annulus (832) between the inner pipe and screen member. The screen member has a cap (860) at its upper end to prevent fluid from escaping from the upper end of the screen member. The cap may have a pop off valve (870) so fluid can escape from the screen member when the screen becomes clogged with debris or pressure builds within the screen member.

  • Patent number: 8302680
    Abstract: Screen assemblies capable of being disposed in a wellbore for hydrocarbon fluid production are described. The screen assemblies can support tubes for receiving hydrocarbon fluid and reduce or eliminate plugging of the tubes by swellable material. A screen assembly may include a support material between a tube and swellable material located exterior to a base pipe. The tube may include perforations and can receive and direct hydrocarbon fluids from the formation. The swellable material can expand after contact with an activating fluid and can displace the tube toward a surface of the bore. The swellable material can expand more than the support material and the support material can reduce or prevent plugging of the perforations by the swellable material expanding.
