发明名称 Method and systems to sever wellbore devices and elements
摘要 A method for performing an operation in the wellbore may include at least partially separating a wellbore tubular while reducing a compression in a section of the wellbore tubular using a force applicator in the wellbore. An apparatus for performing the downhole operation may include a cutter configured to at least partially sever a wellbore tubular; and a force applicator configured to reduce a compression in a section of a wellbore tubular proximate to the cutter.

主权项 1. A method for performing an operation in the wellbore, comprising: gripping a wellbore tubular at two points; urging the two points apart using a force applicator; at least partially separating the wellbore tubular into a first and a second section while reducing a compressive force acting on the wellbore tubular using the force applicator in the wellbore, wherein the wellbore tubular is at least partially separated at a location between the two points.
