  • Downhole tool 2 may include a fluid port 4, which extends through the wall of the tubular housing.
  • the port extends from the inner diameter ID of the tubular housing to the outer surface 2a, thereby, when open, providing fluid access through the wall.
  • the port 4 may have a fluid controller to control aspects of the flow therethrough, such as for example, a nozzle, a screen, a choke such as a limited entry insert, etc.
  • a fluid port cover 10 is installed in the fluid port 4.
  • a closure which in this embodiment is sliding sleeve 8, may be installed to cover the fluid port 4 and may be configurable between a port-closed and a port-open position. The open position exposes the fluid port 4 to fluid flows from the inner diameter.
  • the fluid port cover opens by some failure, because the fluid port cover is formed of erodible material, it may continue to erode provided there is a fluid flow through the port, past the fluid port cover.
  • the fluid port cover 10 may, for example, be formed of metal, polymers, etc. Suitable materials include, but are not limited to, aluminum and steel such as stainless steel or steel alloys.
  • the terms “eroded”, “erodible” or forms thereof mean that the fluid port cover 10 or a portion thereof, exhibits substantial mass or density reduction, or chemical transformation when subjected to maintained fluid contact and possibly flows therepast.

  • solids means those solids that generally exist in a wellbore, result from operations or is added to achieve selected fluid or operational properties, including from/for drilling, stimulation, perforation, cementing operations, etc. Solids, therefore include naturally occurring debris such as rock particles, sand, silts or clays and introduced particles such as cuttings, mud particulate, proppants, etc.
  • Chemical transformation can include oxidation/reduction, hydrolysis, substitution, and/or addition reactions, or other chemical reactions of the material from which the fluid port cover 10 is made.
  • the erosion may be the result of a chemical interaction of the fluid port cover 10 with the environment.
  • the erosion may also be triggered by applying a triggering influence, such as a chemical reactant to the fluid port cover 10 for example, to increase a reaction rate.
  • Stimulation fluids such as fracturing fluids, acids, cleaning chemicals, or proppant laden fluids may also cause or facilitate erosion of the fluid port cover 10.
  • the fluid port cover 10 is formed to gradually separate, split or tear, etc. when exposed to a pressure differential from the first face 12 to the opposite face 14.
  • the failure can be facilitated by a weakened material line 20 on the fluid port cover 10.
  • the material along the line being weaker than the other material of the cover, tends to fail ahead of the other material of the cover.
  • the gradual failure (splitting, separation, tearing, etc.) of the cover 10
  • tearing may be achieved by intersection of lines 20 and/or by varying the form (shape, depth, etc.) of the line along its length and/or by varying the thickness of the body over which the lines 20 extend.
  • the thickness of the cover at the score is substantially less than the thickness of other areas of the cover material lacking scores, this renders the material of the body weaker along the lines than elsewhere.
  • the leak aperture may act as a point at which a fluid flow can pass through the cover, even at pressures less than the failure differential described above.
  • leak aperture 122 provides a point at which erosion can occur and/or where a tear along lines 120 can be initiated.
  • An advantageous position for the leak aperture may be adjacent or through a weakened material line.
  • weakened material line 120 may extend from or through the leak aperture 122.
  • an advantageous position for the leak aperture 122 is in the central portion 140b of the fluid port cover 1 10 where two or more weakened material lines 120 intersect.
  • the leak aperture 122 should preferably be sized to permit a flow of fluid therethrough but without significantly releasing pressure from the inner diameter.
  • the flow of fluid through the leak aperture 122 may have an erosive effect which slowly and gradually opens the port to full flow therethrough.
  • the leak aperture may prevent the suitable failure pressure for the cover from being reached. Thus, erosion may be the primary process by which the cover opens.
  • cover may fail at lines 120. Thus, there is redundancy.
  • leak aperture 122 may also facilitate the initial tearing of the fluid port cover 1 10 to permit a gradual tear to open the fluid port in which cover 1 10 is installed.
  • the leak aperture 122 While a range of different diameters can be used for the leak aperture 122, a diameter of between about 0.5 mm to about 5 mm may be effective in achieving the leak aperture's purposes. While typically circular, the leak aperture 122 can be of other shapes such as, for example, ovals, square, rectangular, hexagonal, star shaped, etc.
  • Figure 4 shows a fluid port cover 210 similar to that of Figure 3B with a score 220 and a leak aperture 222.
  • Cover 210 is installed in a fluid port 204 of a tool 202 with a retainer 224 installed and a seal 236 over the perimeter edges 214a of the fluid port cover 210, leaving the central portion 214b exposed.
  • the retainer 224 includes a ring that fits into a gland 225 in the wall of the port 204.
  • Seal 236 is an O-ring pressed between a flow controller in the form of an annular insert 230 and the perimeter 214a of the fluid port cover 210.
  • the insert 230 is formed as a nozzle to generate a jetting effect on fluid flows passing therethrough.
  • the pressure to initiate the tear may be selected based on the pressure profiles of the process. In one embodiment, the pressure is selected to be greater than the pressure required to move the closure opening tool (ball 9) or to reconfigure, for example open, the closure (sleeve 8). For example, the pressure selected for initiating a tear may be greater than the pressure required to shift a sleeve and greater than that pressure necessary to keep the ball moving through the string. While the pressure for initiating a tear may have any upper limit, consideration may be given to pump pressures attainable and failure parameters of the tools. Generally, the pressure to initiate a tear may be quite reasonable but above the pressure to reconfigure the closures.
  • the tool may be the only tool intended for operation in the well or, as shown in Figures 6A and 6B, there may be a plurality of tools 402a, 402b connected in a string.
  • the tools may be actuated, in turn but in one trip past, by a single fluid conveyed tool, such as ball 409.
  • This closure has a non-collapsible ball seat 41 b on which ball 409 lands and seals so that closure 408b is moved by pressure acting against the ball and the seat.
  • seat 41 1 b retains ball such that the string uphole of ball 409, and in which ports 404 are exposed, can be pressured up.
