Publication number: 20090000787Abstract: An inflow control device is disclosed for use in controlling the flow of fluid into a production tubing in a subterranean wellbore. The device is especially adapted for use with sand screen apparatus, but is modular in that it is manufactured separately from the sand screen apparatus. An inflow control device according to the present invention contains an orifice having an opening which is adjustable in size and which is disposed in the device to permit communication of fluid from one end of the body to the other. An inflow control device according to the present invention may be utilized with multiple sand screen assemblies.Type: ApplicationFiled: June 27, 2007Publication date: January 1, 2009Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Bunker Hill, Mark Fraker, Qing Yao

Publication number: 20060137873Abstract: A viscometer for a down hole tool positionable in a well bore penetrating a subterranean formation is described. The formation contains at least one fluid therein. The down hole tool is adapted to convey at least a portion of the fluid to the viscometer. The viscometer comprises a sensor unit, and at least one magnet. The sensor unit is positionable within the down hole tool and comprises at least two spatially disposed clamps and a wire suspended in tension between the at least two clamps such that the wire is available for interaction with the fluid when the viscometer is positioned within the down hole tool and the down hole tool is positioned within the subterranean formation and receives the fluid from the subterranean formation.Type: ApplicationFiled: December 23, 2004Publication date: June 29, 2006Inventors: Derek Caudwell, Anthony Goodwin, Martin Trusler, Michael Frels, Kai Hsu, Jonathan Brown, Julian Pop, Bunker Hill, Andrew Kurkjian

Publication number: 20050155760Abstract: An apparatus and method for extracting fluid from a subsurface formation is disclosed. A downhole sampling tool is provided with a probe having an internal wall capable of selectively diverting virgin fluids into one or more virgin flow channels for sampling, while diverting contaminated fluids into one or more contaminated flow channels to be discarded. The characteristics of the fluid passing through the channels of the probe may also be measured using techniques, such as optical density, to evaluate various fluid parameters, such as contamination levels. The data generated during sampling may be sent to a controller capable of generating data, communicating and/or sending command signals. The flow of fluid into the downhole tool may be selectively adjusted to optimize the flow of fluid into the channels by adjusting the internal wall within the probe and/or by adjusting the flow rates through the channels.Type: ApplicationFiled: March 9, 2005Publication date: July 21, 2005Inventors: Bunker Hill, Alexander Zazovosky
