Abstract
A downhole tool is configured on a wireline adapter kit in the run-in position is disclosed. The downhole tool comprises a large open bore when the downhole tool is set and the wireline adapter kit is removed, thereby allowing production to commence without removal of the downhole tool. The large bore diameter may be greater than 2 inches for a 4.5 inch casing, or greater than 2.5 inches for a 5.5 inch casing.
Claims20
A downhole tool comprising:
- slips configured to grippingly engage a well casing when the downhole tool is set;
- a cone slidingly engaged with the slips, the cone comprising an open bore through the cone axially aligned with the cone;
- an extrusion limiter engaged by the cone;
- and
- a packer cup element located adjacent to the extrusion limiter and slidingly engaged with the cone.

A method of deploying downhole tool assemblies, the method comprising:
- running a downhole tool assembly into a casing of a wellbore utilizing a mandrel of a wireline adapter kit attached to the downhole tool assembly, wherein the downhole tool comprises:
- slips configured to grippingly engage a well casing when the downhole tool is set,
- a cone slidingly engaged with the slips, the cone comprising an open bore through the cone axially aligned with the cone,
- an extrusion limiter engaged by the cone, and
- a packer cup element located adjacent to the extrusion limiter and slidingly engaged with the upper cone;
- simultaneously creating a pushing force and a pulling force on the downhole tool assembly to set the downhole tool assembly in the casing to create a seal between the downhole tool and the casing;
- removing at least a portion of the wireline adapter kit to leave at least a portion of the downhole tool assembly sealed in the casing, including removing the mandrel of the wireline adapter kit from the downhole tool assembly;
- and
- wherein the cone forms an inner bore in fluid communication with the casing that enables production from the casing.
