Patent number: 8776897Abstract: A hydraulically balanced multiple drop well completion has a plurality of hydraulic control lines each of which communicates hydraulic inputs and a plurality of hydraulically operated tools numbering greater than or equal to the number of hydraulic control lines. Each of the hydraulic control lines is connected to at least one of the hydraulically operated tools to communicate hydraulic inputs to actuate the hydraulically operated tools. Each of the hydraulically operated tools discharges hydraulic fluid to one of the hydraulic control lines other than the hydraulic control line from which it receives the controlling hydraulic input.Type: GrantFiled: January 3, 2011Date of Patent: July 15, 2014Assignee: Schlumberger Technology CorporationInventors: Francesco Vaghi, Ives Loretz

Patent number: 8430162Abstract: A technique facilitates monitoring of conditions which are prone to cause scale precipitation around downhole equipment. The technique also enables a local, downhole reaction to the potential for precipitation of scale. A downhole scale monitoring and inhibition system may be provided with a measurement module and injection module. The measurement module monitors at least one downhole parameter indicative of the potential for scale formation. In response to data output from the measurement module, the injection module is operated to provide downhole, local injections of an inhibitor chemical.Type: GrantFiled: May 25, 2010Date of Patent: April 30, 2013Assignee: Schlumberger Technology CorporationInventors: Spyro Kotsonis, Syed A. Ali, Ives Loretz

Patent number: 7712541Abstract: A technique is provided to temporarily protect well system components during transport, movement downhole and/or initial downhole operations. A sacrificial material is formed as a protective sacrificial element disposed proximate susceptible well system components. The protective sacrificial element is at least partially dissolvable in fluids within a wellbore to facilitate removal of the element after a desired time period. Once the temporary, protective sacrificial element is removed, the protected well system component is fully operable.Type: GrantFiled: November 1, 2006Date of Patent: May 11, 2010Assignee: Schlumberger Technology CorporationInventors: Ives Loretz, Donald Ross

Publication number: 20080110635Abstract: To assemble a well tool, an inventory of plural different types of functional modules is maintained at an assembly location. An order for a well tool having a specified first application is received. In response to the order, a first combination of the plural types of functional modules from the inventory is assembled to form the well tool.Type: ApplicationFiled: November 14, 2006Publication date: May 15, 2008Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ives Loretz, Alok Dwivedi, Pierre Hosatte
