Abstract
A tool to remove portions of casing from a wellbore. A tool may include a bottom sub-assembly and casing that selectively detach from a sub-assembly. This may allow for tools and casing within the wellbore to be efficiently and effectively removed from the wellbore without having to cut tools down well.
Claims20
A detachable tool for a wellbore comprising:
- a bottom sub assembly configured to be coupled to an upper sub assembly;
- the upper sub assembly including a support sleeve and an adjuster sleeve, the adjuster sleeve being decoupled from the bottom sub assembly based on downward linear movement of the support sleeve and inward movement of the adjuster sleeve, wherein a communication bypass is exposed after the downward linear movement of the support sleeve, wherein communication is established from a first area above an object positioned on the support sleeve to a second area below the object positioned on the support sleeve via the communication bypass after the downward linear movement of the support sleeve.
A method for utilizing a detachable tool within a wellbore comprising:
- coupling an upper sub assembly to a bottom sub assembly;
- decoupling the upper sub assembly from the bottom sub assembly based on downward linear movement of a support sleeve and inward movement of an adjuster sleeve, wherein the upper sub assembly includes the support sleeve and the adjuster sleeve;
- exposing a communication bypass between the support sleeve and the adjuster sleeve after the downward linear movement of the support sleeve;
- and
- establishing communication from a first area above an object positioned on the support sleeve to a second area below the object positioned on the support sleeve via the communication bypass after the downward linear movement of the support sleeve.

A method for utilizing a detachable tool for a wellbore comprising:
- coupling an upper sub assembly to a bottom sub assembly;
- restricting rotational movement of the upper sub assembly and the bottom sub assembly in two directions;
- coupling an adjuster sleeve and a support sleeve together via a temporary coupling mechanism at a first location in a first mode, wherein the adjuster sleeve includes a shaft and a collet;
- coupling the adjuster sleeve and the support sleeve together via the collet at a second location in a second mode based on downward linear movement of the support sleeve and inward movement of the adjuster sleeve, wherein an outer diameter of the support sleeve includes a projection, the projection being configured to interface with a no-go on an inner diameter of the bottom sub assembly to limit the downward linear movement of the support sleeve.
