Through tubing intelligent completion and method

Abstract

A through tubing intelligent completion including a completion string; one or more isolation seals on the completion string and having an undeployed set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed; and one or more interventionlessly actuable flow control devices in the completion string having a set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed and method.

1 . A through tubing intelligent completion comprising:
 a completion string;   one or more isolation seals on the completion string and having an undeployed set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed; and   one or more interventionlessly actuable flow control devices in the completion string having a set of dimensions smaller than one or more restrictions in a tubing string through which the completion string is deployed.   
     
     
         2 . A through tubing intelligent completion as claimed in  claim 1  further comprising a control line in operable communication with one or more of the one or more interventionlessly actuable flow control devices. 
     
     
         3 . A through tubing intelligent completion as claimed in  claim 1  wherein the one or more isolation seals are inflatable seals. 
     
     
         4 . A through tubing intelligent completion as claimed in  claim 1  wherein the one or more isolation seals are swellable seals. 
     
     
         5 . A through tubing intelligent completion as claimed in  claim 1  wherein the one or more interventionlessly actuable flow control devices comprises:
 a housing; 
 a fluid bypass channel within the housing; 
 an actuator within the housing; and 
 a valve in operable communication with the actuator. 
 
     
     
         6 . A through tubing intelligent completion as claimed in  claim 5  wherein the actuator is disposed centrally of the housing. 
     
     
         7 . A through tubing intelligent completion as claimed in  claim 5  wherein the bypass is disposed perimetrically of the housing relative to the actuator. 
     
     
         8 . A through tubing intelligent completion as claimed in  claim 5  wherein the valve is a poppet type valve. 
     
     
         9 . A through tubing intelligent completion as claimed in  claim 1  wherein the completion string further includes a wet connect. 
     
     
         10 . A through tubing intelligent completion as claimed in  claim 1  wherein the completion string further includes one or more sensors. 
     
     
         11 . A through tubing intelligent completion as claimed in  claim 1  wherein the completion string further includes a set of one or more ports fluidly communicating the completion string with an annuls thereof. 
     
     
         12 . A method for upgrading an existing well with an intelligent completion comprising:
 making up a completion string as defined in  claim 1 ;   running the completion string into a production tubing string in a borehole;   exiting a downhole end of the production tubing string with the completion string; and   deploying the one of more isolation seals.   
     
     
         13 . A method as claimed in  claim 12  further comprising adjusting one or more of the one or more control devices to optimize production. 
     
     
         14 . A method as claimed in  claim 12  wherein the running is on coil tubing. 
     
     
         15 . A method as claimed in  claim 12  wherein the deploying is by inflating the one or more seals. 
     
     
         16 . A method as claimed in  claim 12  wherein the deploying is by swelling the one or more seals.
