Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
77 words
A method of completing a wellbore, comprising: running in a screen, a gravel pack assembly comprising a flow diversion tool, and a completion string in a first trip; gravel packing the well; and removing the flow diversion tool from the gravel pack assembly and from the completion string, wherein the gravel pack assembly comprises a cross-over port and wherein the cross-over port remains in the wellbore after removing the flow diversion tool from the gravel pack assembly.
Claim 2
Independent Claim
77 words
A method of completing a wellbore, comprising: running in a screen, a gravel pack assembly comprising a flow diversion tool, and a completion string in a first trip; gravel packing the well; and removing the flow diversion tool from the gravel pack assembly and from the completion string, wherein the gravel pack assembly comprises a cross-over port and wherein the cross-over port remains in the wellbore after removing the flow diversion tool from the gravel pack assembly.
Claim 3
Dependent Claim
37 words
The method of claim 1 , wherein removing the flow diversion tool comprises removing the flow diversion tool with one of a sand line, a wire line, a coiled tubing, a slick line, and a pipe string.
Claim 4
Dependent Claim
35 words
The method of claim 1 , further comprising running in a rod pump and a plurality of pump rods in a second trip, without performing any trips between the first trip and the second trip.
Claim 5
Dependent Claim
33 words
The method of claim 1 , further comprising applying fluid pressure down an annulus defined between the wellbore and the completion string to shift a valve seat contained by the flow diversion tool.
Claim 6
Dependent Claim
24 words
The method of claim 4 , wherein the flow diversion tool comprises a stop to locate the valve seat when the valve seat shifts.
Claim 7
Dependent Claim
33 words
The method of claim 1 , further comprising lifting up on the completion string to shift a sleeve within the gravel pack assembly to close a port defined by the gravel pack assembly.
Claim 8
Dependent Claim
14 words
The method of claim 1 , wherein the completion string comprises a mechanical packer.
Claim 9
Dependent Claim
75 words
A well completion tool, comprising: a gravel pack assembly; and a diverter tool releasably coupled to the gravel pack assembly in a run-in state of the completion tool and removable from the gravel pack assembly in a production state of the completion tool, wherein the gravel pack assembly comprises a cross-over port and wherein the cross-over port is configured to remain in a wellbore when the diverter tool is removed from the gravel pack assembly.
Claim 10
Dependent Claim
75 words
A well completion tool, comprising: a gravel pack assembly; and a diverter tool releasably coupled to the gravel pack assembly in a run-in state of the completion tool and removable from the gravel pack assembly in a production state of the completion tool, wherein the gravel pack assembly comprises a cross-over port and wherein the cross-over port is configured to remain in a wellbore when the diverter tool is removed from the gravel pack assembly.
Claim 11
Dependent Claim
21 words
The well completion tool of claim 8 , wherein the diverter tool comprises a first valve coupled to the diverter tool.
Claim 12
Dependent Claim
49 words
The well completion tool of claim 9 , wherein the first valve is retained by a shear retainer in a run-in state of the completion tool and wherein the diverter tool further comprises a stop to locate the first valve in a reverse circulation state of the completion tool.
Claim 13
Dependent Claim
39 words
The well completion tool of claim 8 , wherein the gravel pack assembly further defines a reverse circulate port and further comprises a second valve that blocks fluid flow from outside the completion tool through the reverse circulate port.
Claim 14
Dependent Claim
25 words
The well completion tool of claim 11 , wherein the second valve comprises an elastomeric boot coupled to the outside of the gravel pack assembly.
Claim 15
Dependent Claim
33 words
The well completion tool of claim 8 , wherein the diverter tool changes fluid flow paths through the gravel pack assembly in response to fluid pressure differentials urged upon the gravel pack assembly.
Claim 16
Independent Claim
101 words
A method of wellbore completion, comprising: flowing a gravel slurry out of a gravel pack assembly, the gravel pack assembly comprising a cross-over port; blocking, by a valve coupled to the gravel pack assembly, a reverse fluid flow through the cross-over port to enable a pressure differential to be established that drives a valve seat coupled to the valve to shear retainers and to displace to a shifted position located by stops coupled to the gravel pack assembly; and placing a well associated with the wellbore on production while leaving the cross-over port of the gravel pack assembly in the wellbore.
Claim 17
Independent Claim
101 words
A method of wellbore completion, comprising: flowing a gravel slurry out of a gravel pack assembly, the gravel pack assembly comprising a cross-over port; blocking, by a valve coupled to the gravel pack assembly, a reverse fluid flow through the cross-over port to enable a pressure differential to be established that drives a valve seat coupled to the valve to shear retainers and to displace to a shifted position located by stops coupled to the gravel pack assembly; and placing a well associated with the wellbore on production while leaving the cross-over port of the gravel pack assembly in the wellbore.
Claim 18
Dependent Claim
43 words
The method of claim 14 , wherein the flowing the gravel slurry is performed while flowing a fluid through the cross-over port and up to the surface in an annulus between the wellbore and a production string coupled to the gravel pack assembly.
Claim 19
Dependent Claim
32 words
The method of claim 14 , further comprising running a completion string that includes the gravel pack assembly and a rod pump seat nipple into the wellbore before flowing the gravel slurry.
Claim 20
Dependent Claim
32 words
The method of claim 14 , wherein in an unshifted position the valve seat blocks a flow path from the cross-over port out the gravel pack assembly through a reverse circulate port.
Claim 21
Dependent Claim
32 words
The method of claim 17 , blocking flow from an exterior of the reverse circulate port to an interior of the gravel pack assembly, at least in part, by a reversing boot.
Claim 22
Dependent Claim
29 words
The method of claim 14 , further comprising retrieving the valve seat and valve from the gravel pack assembly and placing a well associated with the wellbore on production.
Claim 23
Dependent Claim
24 words
The method of claim 14 , wherein placing the well on production comprises running in a rod pump and a plurality of pump rods.
