Downhole retrieving tool and method
View Patent ↗Disclosed herein is a downhole retrieving tool. The tool includes, a tubular member with a deformable portion having a reduced internal dimension, and a swage member engagable with the reduced internal dimension such that movement of the swage member through the deformable portion radially increases the internal dimension and the outer surface of the deformable portion causing the deformable portion to move radially outwardly.
1. A method of retrieving a downhole device, comprising:
positioning a deformable portion of a tubular member with an outwardly facing surface thereof downhole of a reduced dimensioned feature of the downhole device to be retrieved;
forcing a swage member through an internal dimension of the deformable portion thereby increasing a radial dimension of the outwardly facing surface such that a greatest radial dimension of the outwardly facing surface is greater than a radial dimension of the reduced dimension feature;
engaging the radial dimension of the reduced dimension feature; and
retrieving the device.
2. The method of retrieving a downhole tubular of claim 1 , further comprising increasing a radial dimension of a plurality of latching members attached to the outwardly facing surface.
3. The method of retrieving a downhole tubular of claim 1 , further comprising increasing a pressure inside the deformable portion to force the swage member through the internal dimension.
