Tools and methods for use in completion of a wellbore

Abstract

A system and method for completing a wellbore using the ported tubular are provided. Ports within the wellbore casing may be opened, isolated, or otherwise accessed to deliver treatment to the formation through the ports, using a tool assembly deployed on tubing or wireline.

What is claimed is: 
     
         1 . A method for shifting a sliding sleeve in a wellbore, comprising:
 providing a valve continuous with a wellbore tubular, the valve comprising a ported housing and a port closure sleeve slidably disposed within the ported housing;   providing a tool assembly comprising: a locating device and a resettable sealing member;   deploying the tool assembly within the wellbore on wireline;   locating the resettable sealing assembly within the port closure sleeve;   setting the sealing member across the sliding sleeve; and   applying a downward force to the sealing member to slide the sleeve with respect to the ported housing.   
     
     
         2 . The method as in  claim 1 , wherein the step of setting the sealing member comprises application of a radially outward force with the sealing member to the sleeve so as to frictionally engage the sleeve with the sealing member. 
     
     
         3 . The method as in  claim 2 , wherein the sleeve comprises an inner surface of uniform diameter along its length, free of any profile. 
     
     
         4 . The method as in  claim 2 , wherein the sleeve has an inner diameter consistent with the inner diameter of the wellbore tubular. 
     
     
         5 . The method as in  claim 1 , wherein the step of applying a downward force to the sealing member comprises delivering fluid to the wellbore to increase the hydraulic pressure above the sealing member. 
     
     
         6 . The method as in  claim 5 , wherein the port closure sleeve is initially retained in a closed position with respect to the ported housing by a hydraulic pressure above the sealing member generated by the fluid delivery is sufficient to exceed a threshold force required to overcome said retention. 
     
     
         7 . The method as in  claim 6 , wherein the port closure sleeve is retained by a mating profile on the outer surface of the sleeve and the inner surface of the valve housing. 
     
     
         8 . The method as in  claim 6 , wherein the port closure sleeve is retained by a set screw. 
     
     
         9 . The method as in  claim 1 , further comprising the step of applying treatment fluid through the valve port to an adjacent geological formation. 
     
     
         10 . The method as in  claim 9 , further comprising the step of monitoring hydraulic pressure at the sealing element during treatment. 
     
     
         11 . The method as in  claim 10 , wherein the monitoring step comprises receiving sensed measurements from at surface during treatment. 
     
     
         12 . A tool assembly deployed on wireline for use in actuating a sliding sleeve within a tubular, the tool assembly comprising: a logging tool; a resettable sealing assembly comprising a pressure sensor; and a pump down plug depending from the sealing assembly. 
     
     
         13 . The tool assembly as in  claim 12 , wherein the pump down plug is detachable from the tool assembly. 
     
     
         14 . The tool assembly as in  claim 12 , wherein the pump down plug is retractable. 
     
     
         15 . The tool assembly as in  claim 12 , wherein the resettable sealing assembly comprises a compressible sealing member. 
     
     
         16 . The tool assembly as in  claim 12 , wherein the tubular is wellbore casing or liner. 
     
     
         17 . The tool assembly as in  claim 12 , wherein the sealing assembly remains attached to the wireline during operation.
