Abstract
Abstract A well completion method performed in a single trip into a well includes inserting a service tool into the well to a desired location; gravel packing the well; and circulating fluids within the wellbore through the service tool to dislodge and remove filter cake residue. A method of completing a subterranean well performed in a single trip into a wellbore includes running a service tool into the well, the service tool defining multiple, selectable flow paths; gravel packing the well; selecting a different flow path of the service tool; removing a filter cake from the wellbore by circulating a fluid through the service tool; spotting specially fluids within the wellbore at desired locations; and removing the service string from the well.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
45 words
A well completion method performed in a single trip into a well comprising: inserting a service tool into the well to a desired location; gravel packing the well; and circulating fluids within the wellbore through the service tool to dislodge and remove filter cake residue.
Claim 2
Dependent Claim
45 words
A well completion method performed in a single trip into a well comprising: inserting a service tool into the well to a desired location; gravel packing the well; and circulating fluids within the wellbore through the service tool to dislodge and remove filter cake residue.
Claim 3
Dependent Claim
30 words
The method of claim 1 , wherein the gravel packing of the well comprises flowing a gravel laden slurry through the service tool, thereby selectively depositing gravel within the well.
Claim 4
Dependent Claim
15 words
The method of claim 1 , wherein the service tool defines multiple, selectable flow paths.
Claim 5
Dependent Claim
27 words
The method of claim 3 , wherein the service tool is inserted into the well in a first flow path configuration allowing circulation through the service tool.
Claim 6
Dependent Claim
37 words
The method of claim 4 , wherein when the service tool has been inserted to the desired location, the service tool is reconfigured to a second flow path configuration to enable the gravel packing of the well.
Claim 7
Dependent Claim
45 words
The method of claim 5 , wherein after the well has been gravel packed, the service tool is reconfigured to a third flow path configuration to enable the circulation of fluids within the wellbore, through the service tool, to dislodge and remove filter cake residue.
Claim 8
Dependent Claim
29 words
The method of claim 6 , wherein after the circulation of fluids to dislodge and remove filter cake residue, specialty fluids are spotted at selected locations within the well.
Claim 9
Independent Claim
76 words
A method of completing a subterranean well performed in a single trip into a wellbore comprising: running a service tool into the well, the service tool defining multiple, selectable flow paths; gravel packing the well; selecting a different flow path of the service tool; removing a filter cake from the wellbore by circulating a fluid through the service tool; spotting specialty fluids within the wellbore at desired locations; and removing the service string from the well.
Claim 10
Independent Claim
76 words
A method of completing a subterranean well performed in a single trip into a wellbore comprising: running a service tool into the well, the service tool defining multiple, selectable flow paths; gravel packing the well; selecting a different flow path of the service tool; removing a filter cake from the wellbore by circulating a fluid through the service tool; spotting specialty fluids within the wellbore at desired locations; and removing the service string from the well.
Claim 11
Dependent Claim
30 words
The method of claim 8 , wherein the gravel packing of the well comprises flowing a gravel laden slurry through the service tool, thereby selectively depositing gravel within the wellbore.
Claim 12
Dependent Claim
28 words
The method of claim 9 , wherein the service tool is inserted into the well in a first flow path configuration allowing fluid circulation through the service tool.
Claim 13
Dependent Claim
37 words
The method of claim 10 , wherein when the service tool has been inserted to the desired location, the service tool is reconfigured to a second flow path configuration to enable the gravel packing of the well.
Claim 14
Dependent Claim
64 words
A well completion method performed in a single trip into a well comprising: inserting a service tool into the well to a desired location; gravel packing the well with a fluid that contains at least one breaker for filtercake removal; and circulating or injecting fluids within the well through the service tool to displace the at least one breaker away from predetermined downhole equipment.
Claim 15
Dependent Claim
64 words
A well completion method performed in a single trip into a well comprising: inserting a service tool into the well to a desired location; gravel packing the well with a fluid that contains at least one breaker for filtercake removal; and circulating or injecting fluids within the well through the service tool to displace the at least one breaker away from predetermined downhole equipment.
Claim 16
Dependent Claim
28 words
The method of claim 12 , wherein the service tool is inserted into the well in a first flow path configuration allowing fluid circulation through the service tool.
Claim 17
Dependent Claim
37 words
The method of claim 12 , wherein when the service tool has been inserted to the desired location, the service tool is reconfigured to a second flow path configuration to enable the gravel packing of the well.
Claim 18
Dependent Claim
38 words
The method of claim 12 , wherein when the gravel packing of the well has been performed, the service tool is reconfigured to a third flow path configuration to enable the circulating of fluids through the service tool.
