Abstract

A system for deploying downhole components includes a housing apparatus comprising a tool chamber configured to house a plurality of downhole tools and a conveyance configured to run the housing apparatus along the wellbore. The housing apparatus is secured to an end of the conveyance. The system for deploying downhole components also includes an actuation mechanism configured to selectively eject individual downhole tools of the plurality of downhole tools from the housing apparatus at respective locations in the wellbore.

First claim

What is claimed is:

1. A system for deploying downhole components, comprising:
a housing apparatus comprising a tool chamber configured to house a plurality of downhole tools;
a conveyance configured to run the housing apparatus along a wellbore, wherein the housing apparatus is secured to an end of the conveyance; and
an actuation mechanism configured to selectively eject individual downhole tools of the plurality of downhole tools from the housing apparatus at respective locations in the wellbore, wherein the actuation mechanism comprises a plurality of balls, wherein each ball of the plurality of balls comprises a unique diameter corresponding to the unique diameter of a respective downhole tool, and wherein each ball of the plurality of balls is configured to be selectively released into the housing apparatus and received by the respective downhole tool to block fluid flow through the housing apparatus and increase pressure in the housing apparatus, wherein the increased pressure is configured to cause the respective downhole tool to slide axially out of the housing apparatus at the respective location in the wellbore, and wherein fluid is configured to circulate through the actuation mechanism and the housing apparatus after ejecting all of the plurality of downhole tools from the housing apparatus.

2. The system of claim 1 , further comprising a retention device positioned proximate an opening in a lower axial end of the housing apparatus, wherein the retention device is configured to at least partially restrain at least one downhole tool of the plurality of downhole tools from sliding axially toward the opening in the lower axial end.

3. The system of claim 1 , further comprising the plurality of downhole tools secured in the tool chamber within the housing apparatus, wherein each downhole tool of the plurality of downhole tools comprises a respective flow channel having a unique diameter, wherein the plurality of downhole tools are secured within the housing apparatus in an ascending order of the respective diameters of flow channels, and wherein a first downhole tool with a smallest diameter flow channel is secured proximate an opening in a lower axial end of the housing apparatus and a last downhole tool having the largest diameter flow channel is secured axially uphole in the housing apparatus with respect to the first downhole tool.

4. The system of claim 1 , wherein the conveyance comprises coiled tubing, segmented drill piping, or some combination thereof.

5. A system for deploying downhole components, comprising:
a housing apparatus comprising a tool chamber configured to house a plurality of downhole tools;
a conveyance configured to run the housing apparatus along a wellbore, wherein the housing apparatus is secured to an end of the conveyance; and
an actuation mechanism configured to selectively eject individual downhole tools of the plurality of downhole tools from the housing apparatus at respective locations in the wellbore, wherein the actuation mechanism comprises a continuous screw mechanism having a rotating helical screw blade, wherein the rotating helical screw blade is positioned within the housing apparatus, and wherein fluid is configured to circulate through the actuation mechanism and the housing apparatus after ejecting all of the plurality of downhole tools from the housing apparatus.

6. The system of claim 5 , wherein the actuation mechanism comprises an electric motor configured to drive rotation of the rotating helical screw blade.

7. The system of claim 5 , wherein the actuation mechanism is electrically coupled to a control system disposed at a surface of the wellbore via a wired connection, and wherein the actuation mechanism is configured to actuate the rotating helical screw blade in response to electrical signals from the control system.

8. A system for deploying downhole components, comprising:
a housing apparatus comprising a tool chamber configured to house a plurality of downhole tools;
a conveyance configured to run the housing apparatus along a wellbore, wherein the housing apparatus is secured to an end of the conveyance; and
an actuation mechanism configured to selectively eject individual downhole tools of the plurality of downhole tools from the housing apparatus at respective locations in the wellbore,, wherein the actuation mechanism comprises an inner housing disposed within an outer housing of the housing apparatus, wherein the inner housing is configured to slide axially with respect to the outer housing, and wherein a first axial end of the inner housing is configured to push at least one downhole tool of the plurality of downhole tools toward an opening in a lower axial end of the outer housing, and wherein fluid is configured to circulate through the actuation mechanism and the housing apparatus after ejecting all of the plurality of downhole tools from the housing apparatus.

9. The system of claim 8 , wherein the inner housing is configured to slide axially toward the opening in a lower axial end of the outer housing in response to pressure from a fluid flow through the conveyance.

10. The system of claim 8 , wherein the outer housing comprises a plurality of fluid exhaust ports, wherein at least a first exhaust port and a second exhaust port are axially offset along the outer housing, wherein the first exhaust port is configured to exhaust fluid flow in a first position of the inner housing with respect to the outer housing, and wherein the first exhaust port and the second exhaust port are configured to exhaust fluid flow in a second position of the inner housing with respect to the outer housing.

11. The system of claim 8 , wherein the actuation mechanism comprises a spiraled J-slot mechanism, wherein the spiraled J-slot mechanism is configured to control movement of the inner housing with respect to the outer housing to selectively eject the individual downhole tools.

12. The system of claim 11 , wherein the spiraled J-slot mechanism is configured to incrementally slide the inner housing axially toward the opening in a lower axial end of the outer housing in response to intermittent fluid flow through the conveyance.

13. A system for deploying downhole components, comprising:
a housing apparatus, wherein the housing apparatus comprises:
an outer housing;
a tool chamber disposed within the outer housing and configured to house a plurality of downhole tools;
an upper axial end configured to couple to a conveyance for running the housing apparatus along a wellbore;
a fluid chamber formed within the outer housing proximate the upper axial end;
a plurality of exhaust ports extending through the outer housing from the fluid chamber to a wellbore, wherein the exhaust ports are axially offset from each other along the outer housing;
a lower axial end disposed opposite the upper axial end and having an opening extending from an exterior of the lower axial end to the tool chamber; and
a central passageway extending from an opposite end of the tool chamber to an opening in the upper axial end; and

an actuation mechanism secured within the housing apparatus and configured to selectively eject individual downhole tools of the plurality of downhole tools from the housing apparatus at respective locations in the wellbore in response to fluid communication received via the conveyance, wherein the actuation mechanism comprises an inner housing configured to eject the downhole tools via sliding axially along the outer housing to push the plurality of downhole tools out of the housing apparatus in response to pressure in the fluid chamber exceeding a threshold pressure, and wherein each exhaust port of the
