Claims22
A conveyance device for use in a well comprising an inner tubular disposed in an outer tubular to form an annular passageway therebetween such that fluid is transported through the annular passageway to bypass a region of the well.
A conveyance device for use in a well comprising one or more flow tubes disposed on a tubular to transport fluid past a region in the well.
A completion apparatus for use in a wellbore comprising:
- an upper tubular having a central passageway therethrough;
- a packer mounted on a lower end of the upper tubular;
- a crossover joined to the upper tubular below the packer and through which fluid flowing in the central passageway can exit the central passageway;
- and
- a conveyance device mounted to the crossover to convey fluid past an enlarged region in the wellbore.
A method to bypass a region in a well comprising:
- providing a closed flowpath that extends from above the region to below the region;
- and
- pumping a fluid into the well such that the fluid enters the flowpath above the region and exits the flowpath below the region.
A gravel pack system for use in a well comprising:
- an upper tubing disposed in the well;
- a conveyance device attached to the upper tubing to convey fluid past a portion of the well;
- and
- a screen below the bypassed portion of the well attached to the conveyance device or a lower tubing.
A method to gravel pack a well having an enlarged region comprising:
- placing a conveyance device in the vicinity of the enlarged region;
- pumping a slurry through the conveyance device such that little or no slurry enters the enlarged region from above;
- and
- depositing gravel carried by the slurry in an annular region between a screen and the well below the conveyance device.
