Abstract

A cross over tool includes, a first tubular forming part of a structure having a channel formed radially through a wall thereof and having a passageway formed longitudinally through the wall. The tool includes a second tubular forming part of a tool string, the second tubular is positionable radially of the first tubular, and has a port through a wall thereof, the port is alignable with the channel. The crossover tool is configured such that while the a port is aligned with the a channel fluid can flow through an inside of the tool string radially through the a port and the a channel and back into the inside of the tool string and through the a passageway and through an annular space defined between the tool string and the structure.

First claim

What is claimed is:

1. A crossover tool, comprising:
a first tubular forming part of a structure, the first tubular having at least one channel formed radially through a wall of the first tubular and having at least one passageway formed longitudinally through at least a portion of the wall of the first tubular, wherein the first tubular includes a first alignment feature; and
a second tubular forming part of a tool string, the second tubular being positionable radially of the first tubular, the second tubular being selectively detachable from the first tubular while downhole and having at least one port through a wall of the second tubular, the second tubular including a second alignment feature, the at least one port being rotationally alignable with the at least one channel, the first tubular being maintainable within the structure while the second tubular is removable from the first tubular and the structure, the crossover tool being configured such that while the at least one port is rotationally aligned with the at least one channel through an interaction between the a first alignment feature and the second alignment feature so that fluid can flow through an inside of the tool string radially through the at least one port and the at least one channel and back into the inside of the tool string and through the at least one passageway and through an annular space defined between the tool string and the structure.

2. The crossover tool of claim 1 , wherein the structure is positioned within a borehole in an earth formation.

3. The crossover tool of claim 1 , further comprising at least one seal that is sealingly engagable between the tool string and the structure to separate at least the annular space from being in fluidic communication directly with at least one of the at least one port or the at least one channel.

4. The crossover tool of claim 3 , wherein the at least one seal is three seals at least two of the three seals being axially spaced from one another along the toolstring.

5. The crossover tool of claim 4 , wherein return flow flows through the inside of the tool string radially between two of the three seals and into the at least one passageway.

6. The crossover tool of claim 1 , wherein a portion of the second tubular having the at least one port is made of a material more resistant to erosion than a material of the first tubular having the at least one channel.

7. The crossover tool of claim 6 , wherein the portion of the second tubular is made of carbide.

8. The crossover tool of claim 1 , wherein the at least one port redirects longitudinal flow to be more radial.

9. The crossover tool of claim 1 , wherein the flow is a slurry.

10. The crossover tool of claim 1 , wherein the at least one port is a plurality of ports distributed perimetrically about the second tubular and the at least one channel is a plurality of channels distributed perimetrically about the first tubular.

11. The crossover tool of claim 1 , wherein at least one of the first alignment feature and the second alignment feature defines a helical groove.

12. The crossover tool of claim 1 , wherein a seat disposed at the second tubular when plugged by a plug causes longitudinal flow through the second tubular to flow outward through the at least one port.

13. A method of making a crossover tool, comprising:
positioning a first tubular having a first alignment feature and at least one channel extending radially through a wall of the first tubular and at least one passageway extending longitudinally through at least a portion of the wall of the first tubular within a structure;
removably positioning a tool string including a second tubular having a second alignment feature and at least one port through a wall of the second tubular within the structure such that the at least one port is rotationally aligned with the at least one channel through an interaction between the a first alignment feature and the second alignment feature, the second tubular being removable from the structure while downhole; and
establishing fluidic communication between the at least one passageway and an annular space defined between the tool string and the structure such that fluid can flow through an inside of the tool string, radially through the at least one port and the at least one channel and back into the inside of the tool string through the at least one passageway and into an annular space between the tool string and the structure.

14. The method of making a crossover tool of claim 13 , further comprising positioning the structure within a borehole in an earth formation.

15. The method of making a crossover tool of claim 14 , further comprising disposing a seat at the tool string below the at least one port.

16. The method of making a crossover tool of claim 15 , further comprising fluidically connecting an inside of the second tubular below the seat to the at least one passageway.
