Publication number: 20120003111Abstract: A mechanism for moving elements in a fluid filled housing a pump with the element to be moved attached rigidly to the pump or to a port assembly connected to the pump. The pump assembly or port assembly moves as a result of differential pressure created between a first and a second chamber separated from each other by the pump assembly or port assembly. Movement of the fluid in one direction increases or decreases pressure, the pressure change resulting in a net force in one direction or the other.Type: ApplicationFiled: June 30, 2010Publication date: January 5, 2012Applicant: Schlumberger Technology CorporationInventors: Kuo-Chiang Chen, Aaron Jacobson, Nathaniel Wicks, Murat Ocalan

Patent number: 7950590Abstract: An actuator is disclosed which operates on the principle of the variable magnetic properties of materials with respect to temperature. As temperature is raised past Curie temperature, magnetic permeability of certain materials drops significantly to a value close to free space permeability. However, depending on the material selection, magnetic permeability may be significantly higher below Curie temperature. This principle is used to cause magnetic attractive force to move an actuator at one temperature, while permitting a return spring force to move the actuator at another temperature by changing the pathway traversed by most magnetic lines of flux from a magnetic source. The actuator may be employed to provide a temperature activated electrical switch or fluid valve. The temperature activated valves are suited to use in high temperature environments, such as SAGD wells.Type: GrantFiled: March 14, 2008Date of Patent: May 31, 2011Assignee: Schlumberger Technology CorporationInventors: Murat Ocalan, Kuo Chiang Chen

Patent number: 7906861Abstract: Electrical energy is produced at a remote site by converting kinetic energy from the environment. The kinetic energy may include vibrations and flow of fluid. In some embodiments the kinetic energy causes magnets to move with respect to coils in order to produce electrical energy. An anchor holds the device in place, and permits the device to be retrieved or relocated. A flexure or compliant membrane that helps determine the position of the magnets with respect to coils is defined by mechanical properties that permit oscillatory movement in response to the inputted kinetic energy. The device can be tuned to different vibration and flow regimes in order to enhance energy conversion efficiency. Further, the device may be mounted in a secondary flow path such as a side package or annular tube.Type: GrantFiled: November 28, 2007Date of Patent: March 15, 2011Assignee: Schlumberger Technology CorporationInventors: Julio C.
