Patent number: 7903915Abstract: A cable is provided including an inner member, an outer member and an intermediate member. The intermediate member may be positioned between the inner member and the outer member and include a number of disconnection sections spaced apart from one another. In some cases, the cable may include two or more inner members. In addition, a method for preparing an end of a cable may be provided, including the steps of removing a portion of an outer member of the cable and applying a tensile force to an intermediate member of the cable comprising a plurality of disconnection sections. The intermediate member of the cable may be sheared at one of the plurality of disconnection sections, thereby exposing a portion of an inner member of the cable.Type: GrantFiled: May 20, 2009Date of Patent: March 8, 2011Assignee: Schlumberger Technology CorporationInventors: Ramaswamy Meyyappan, Michael Alff, Arunkumar Arumugam

Patent number: 7886835Abstract: A kickover tool is for placing and extracting a valve in a mandrel having a tool body extending in a longitudinal direction and having a hydraulic piston chamber therein. A hydraulic piston is located inside the hydraulic piston chamber. A kickover arm portion is mechanically connected to the hydraulic piston, the kickover arm portion comprising a kickover arm having a tool portion. The kickover arm has a non-kicked-over position where the kickover arm is substantially coaxial with the longitudinal direction and a kicked-over position where the kickover arm is substantially non-coaxial with the longitudinal direction. The kickover arm moves to the kicked-over position upon extension of the hydraulic piston.Type: GrantFiled: August 31, 2007Date of Patent: February 15, 2011Assignee: Schlumberger Technology CorporationInventors: Arunkumar Arumugam, Tyson Messick, Steven Anyan, Kenneth C.
