Patent number: 9140086Abstract: A downhole apparatus for depositing a tool in a side pocket mandrel is described. The apparatus comprises an apparatus body, a tool holder and a displacement mechanism for connecting the tool holder to the apparatus body. The tool holder is movable between a run-in position, in which the tool holder is adjacent the body, to a displaced position, in which the tool holder is spaced away from the body. As a tool is moved between the run-in position and the displaced position, a tool longitudinal axis remains substantially parallel to an apparatus body longitudinal axis.Type: GrantFiled: October 12, 2011Date of Patent: September 22, 2015Assignee: Wireline Engineering LimitedInventor: Robert Neil Hall
