Wellbore tool and method of use

Abstract

A wellbore tool includes an elongated lower body having a first section and a second section, the second section having an interior channel; an upper body having a first section and a second section, the second section to extend into the interior channel of the elongated lower body; a connection to secure the second section of the upper body within the interior channel; a seal extending around an interior periphery of the interior channel; the lower body is to be attached to a liner within the wellbore; and the upper body is to be rotated via the connection from a closed configuration to a circulating configuration; and the upper body is to be rotated via the connection from the closed configuration to a released configuration.

What is claimed is: 
     
         1 . A wellbore tool, comprising:
 an elongated lower body having a first section and a second section, the second section having an interior channel;   an upper body having a first section and a second section, the second section configured to extend into the interior channel of the elongated lower body;   a connection configured to secure the second section of the upper body within the interior channel;   a seal extending around an interior periphery of the interior channel   wherein the lower body is configured to be attached to a liner within the wellbore; and   wherein the upper body is configured to be rotated via the connection from a closed configuration to a circulating configuration; and   wherein the upper body is configured to be rotated via the connection from the closed configuration to a released configuration.   
     
     
         2 . The wellbore tool of  claim 1 , wherein the connection is a threaded connection with a plurality of connector threads. 
     
     
         3 . The wellbore tool of  claim 1 , wherein a first predetermined number of left-handed rotations opens the wellbore tool to the circulating configuration. 
     
     
         4 . The wellbore tool of  claim 1 , wherein a second number of left-handed rotation opens the wellbore tool to the released configuration. 
     
     
         5 . The wellbore tool of  claim 1 , wherein a first predetermined number of right-handed rotations closes the wellbore tool from the circulating configuration. 
     
     
         6 . A method of well construction, comprising:
 providing a tool having a lower body with an interior channel and an upper body configured to engage within the interior channel via a connection, the tool having a seal extending between the interior channel and the upper body;   cementing a parent casing string at a predetermined depth within a wellbore;   creating a drilled section below a lower end of the parent casing;   running a production string with the tool into the wellbore such that the tool is positioned above a shoe of the parent casing;   performing cementing operations through the production string;   applying a first number of left-hand rotations to the upper body of the tool, thereby converting the tool to a circulation configuration;   performing circulation operations to clean excess cement above the tool;   applying a predetermined number of right-hand rotations to the upper body to convert the tool to a closed configuration for pumping operations;   performing pumping operations; and   applying a second number of left-hand rotations to the upper body to convert the tool to a released configuration, such that the upper body is released from the lower body by being completely disengaged with the connection;   wherein the lower body remains attached to a liner within the wellbore.   
     
     
         7 . The method of  claim 6 , wherein the connection is a threaded connection with a plurality of connector threads.
