Patent number: 9637998Abstract: A valve system for ensuring well closure upon exposure to a predetermined condition even where a well access line is disposed through the valve. This system may be configured with a supplemental power supply capable of effectuating a cutting closure of the valve. Thus, any obstructing well access line such as coiled tubing may be cut during closure to ensure sealing off of the well, even if the cutting mechanism is separated from its traditional power supply by shear or parting of a portion of the landing string. Once more, the supplemental power sufficient for a cutting closure is only provided in the event of a predetermined condition such as the emergence of a potentially hazardous tubular separation.Type: GrantFiled: July 27, 2015Date of Patent: May 2, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: David Carter Allensworth, Josh Rayner

Patent number: 8672029Abstract: A technique facilitates mixing operations by removing foaming that results from air entrained during mixing of constituents. A mixing system comprises a container body having an interior and an inlet through which material enters the interior for mixing. The container body also comprises a discharge through which the mixed material is delivered downstream. A mechanical foam breaker is disposed within the container body and extends upwardly a sufficient distance to extend through a surface level to which the material rises during mixing within the container body. The mechanical foam breaker is oriented to break down foam along the surface of the material as the material moves through the interior.Type: GrantFiled: December 30, 2009Date of Patent: March 18, 2014Assignee: Schlumberger Technology CorporationInventors: Brian Goddard, Josh Rayner, Michael Woodmansee, Philip Zsiga

Patent number: 8596056Abstract: A configurable hydraulic system facilitates a variety of oilfield cementing and other oilfield or related applications. The system employs a plurality of prime movers to drive a plurality of loads. The plurality of prime movers and loads are coupled with a configurable hydraulic system that maintains a separate, sealed hydraulic system associated with each prime mover. The configurable hydraulic system also enables the load configuration driven by each prime mover to be changed without losing the benefit of a separate, sealed hydraulic system associated with each specific prime mover.Type: GrantFiled: October 2, 2009Date of Patent: December 3, 2013Assignee: Schlumberger Technology CorporationInventors: Michael Woodmansee, Philip Zsiga, Josh Rayner

Patent number: 7775106Abstract: A system and method for using a probe-based guided-wave radar sensor to measure fluid level in a container in a non-contact mode are provided. The system and method of the current invention replaces a wall section of the fluid container, such as a steel slurry tub with a panel of radar-transparent material, such as plastic. The level probe is mounted external to the container, adjacent to the radar-transparent panel. By avoiding contact between the sensor probe and the fluid, whether the fluid be cement slurry or another fluid prone to probe degradation, it is possible to eliminate the possibility of contamination, build-up, caking and/or damage to the probe along with the associated degradation in sensor performance.Type: GrantFiled: February 1, 2008Date of Patent: August 17, 2010Assignee: Schlumberger Technology CorporationInventors: Josh Rayner, Michael Woodmansee

Patent number: 7740447Abstract: A centrifugal pump for abrasive fluid. The pump may include a bearing housing mounted to a tank containing an abrasive fluid. The bearing housing may house wear-susceptible components in a manner distancing and isolating the components from the fluid. A shaft may be coupled to the bearing housing and disposed through the tank to an impeller for dispensing the abrasive fluid beyond the centrifugal pump. Additionally the impeller itself may be housed within an impeller housing that is mechanically coupled to the bearing housing in order to enhance dimensional stability therebetween. Such a centrifugal pump may be coupled to other pumps such as higher pressure positive displacement pumps. In these circumstances the centrifugal pump may be used to facilitate the mixing of the abrasive fluid and provide a degree of pressurization thereto in advance of the fluid's use at an operation site.Type: GrantFiled: January 10, 2007Date of Patent: June 22, 2010Assignee: Schlumberger Technology CorporationInventors: Jean-Louis Pessin, Josh Rayner, Laurent Coquilleau, Michael Woodmansee
