Patent number: 8757254Abstract: A method for controlling drilling fluid rate in a wellbore is disclosed. A drill string is disposed into the well and connected to a formation testing or sampling tool. Drilling fluid is circulated at a first rate through the drill string. Data related to the wellbore, a formation about the wellbore or the formation sampling tool is transmitted to a processor. Upon analysis of the data, the drilling fluid circulation rate is changed to a second rate that is different from the first rate.Type: GrantFiled: August 17, 2010Date of Patent: June 24, 2014Assignee: Schlumberger Technology CorporationInventors: Steven G. Villreal, Julian J. Pop, Vladimir Vaynshteyn

Patent number: 8672031Abstract: Embodiments of the invention include methods and systems for perforating a well using a wired work string assembly. According to embodiments of the invention, the method includes positioning a wired work string assembly in a wellbore, the work string assembly comprising a plurality of wired pipe communicatively coupled at each joint, a depth correlation tool, and a perforating gun assembly. A depth of the perforating gun assembly is determined from a depth correlation tool positioned within the wellbore, and an electrical signal related to the depth of the perforating gun assembly is transmitted to a surface above the wellbore. Firing of the perforating gun assembly is initiated via a signal transmitted from the surface above the wellbore. An electrical signal from the wellbore is transmitted to the surface to confirming the firing of perforating gun assembly. The system includes various tools for perforating the well using the disclosed methods.Type: GrantFiled: March 15, 2010Date of Patent: March 18, 2014Assignee: Schlumberger Technology CorporationInventor: Vladimir Vaynshteyn

Patent number: 8336629Abstract: A technique enables a simplified approach for providing subsea hydraulic control. A subsea installation comprises one or more devices that are actuated hydraulically. A simple signal carrier, such as a wireline logging cable, can be routed down to the subsea installation. However, hydraulic fluid for controlling the one or more hydraulic devices in the subsea installation is delivered via an open water umbilical that extends to the subsea installation from a separate workover control system.Type: GrantFiled: October 2, 2009Date of Patent: December 25, 2012Assignee: Schlumberger Technology CorporationInventors: Vladimir Vaynshteyn, Joseph D.
