Patent number: 9863202Abstract: Systems and methods for using propellant as a force generator in component actuation are disclosed. One embodiment may take the form of a method including deploying at least one component to a subsea location, controlling operation of the at least one component using a control system, and igniting a propellant. The ignition of the propellant actuates the at least one component. Another embodiment may take the form of a subsea system including a control system, a propellant system in communication with the control system, and a component in communication with the propellant system. The propellant system is ignitable by the control system upon receipt of a ignite signal and upon losing communication with the control system after being placed in an armed state by the control system. The component is actuatable by the propellant system after ignition of the propellant system.Type: GrantFiled: December 5, 2014Date of Patent: January 9, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Gary L. Rytlewski, Laure Mandrou, David Allensworth, Quangen Du, Deepak Dcosta

Patent number: 9528328Abstract: A tensions compensator assembly for a slip type joint in an offshore work string. The assembly includes a chamber at the joint which is constructed in a manner to offset or minimize a pressure differential in a production channel that runs through the work string. Thus, potentially very high pressures running through the string are less apt to prematurely force actuation and expansiveness of the slip joint. Rather, the expansive movement of the joint is more properly responsive to heave, changes in offshore platform elevation and other outside forces of structural concern.Type: GrantFiled: November 8, 2012Date of Patent: December 27, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Gary L. Rytlewski, Laure Mandrou, Peter Nellessen, Jr.

Publication number: 20090243875Abstract: A technique facilitates control over multiple well tools. Multiple well tools can be actuated between operational positions. The well tools are coupled to a plurality of multidrop modules with each multidrop module typically being coupled to one or two well tools. Control lines are connected the multidrop modules, and the multidrop modules have the capability of controlling a number of well tools greater than the number of control lines. Each well tool can be actuated individually by providing pressure inputs through one or more of the control lines.Type: ApplicationFiled: March 26, 2008Publication date: October 1, 2009Applicant: Schlumberger Technology CorporationInventors: Laure Mandrou, Michael J.
