Patent ID: 6880636

Claim:
A method for creating a plug in a wellbore, comprising the steps of: coupling a first section of a downhole tool between the lower end of a workstring and a second section of the tool; injecting a slurry for forming the plug into the workstring such that the slurry flows through the downhole tool and exits at a predetermined location within the wellbore; introducing a flow prevention mechanism into the workstring to prevent fluid flow from exiting the first section when the first section is uncoupled from the second section; pressurizing a fluid in the workstring; uncoupling the first section from the second section in response to the step of pressurizing the fluid, wherein the second section remains with the slurry to create the plug in the wellbore and the first section maintains the fluid within the workstring; providing a collet coupled to the second section, wherein the collet is adapted to contract radially from a first position to a second position, wherein in the first position the collet is also coupled to the first section; providing a support mechanism to radially support the collet such that the collet remains in the first position; and providing a positioning mechanism to keep the support mechanism positioned such that the collet remains in the first position.
