Additionally, a method of operating a casing spear may comprise inserting a casing spear into a casing, rotating a mandrel of the casing spear, applying a torque to a slip assembly of the casing spear with the casing, opposing the rotation of the mandrel, and applying a force in a radial direction to at least one slip of a slip assembly of the casing spear in response to the torque.Type: GrantFiled: October 24, 2011Date of Patent: December 30, 2014Assignee: Baker Hughes IncorporatedInventors: Larry T. Palmer, Dennis E. Kroll, Gregory L. Hern

Patent number: 8919459Abstract: A system for controlling a first module, a second module, and a third module. The system includes: an inlet configured to receive fluid from a fluid source; a first double-stage valve; and a second double-stage valve. The first double-stage valve is actuatable to a first position wherein fluid from the inlet flows through the first double-stage valve to the second double-stage valve and a second position wherein fluid from the inlet flows through the first double-stage valve to the third module. The second double-stage valve is actuatable to a first position wherein fluid flows from the first double-stage valve to the first module and a second position wherein fluid flows from the first double-stage valve to the second module.Type: GrantFiled: August 11, 2009Date of Patent: December 30, 2014Assignee: Schlumberger Technology CorporationInventor: Oleg Polyntsev

Patent number: 8915303Abstract: A method of servicing an electric submersible pump in a well with a positive wellhead pressure includes providing production tubing in the well casing, a coil tubing string within the production tubing having an electric submersible pump at a downhole end of the coil tubing string, and a pump-receiving housing above the injection port of the wellhead. With the injection port sealed and the pump-receiving housing opened, the electric submersible pump may be inserted or removed from the pump-receiving housing. With the pump-receiving housing closed and the injection port opened, the electric submersible pump may be moved to or from the production tubing in the well.Type: GrantFiled: September 8, 2010Date of Patent: December 23, 2014Assignee: Petrospec Engineering Ltd.Inventor: Gerald Chalifoux
