Patent number: 7938179Abstract: A sensor and transmitter is employed with a pressurized chamber of a downhole tool to be able to tell at a glance when the tool is delivered for service that it is properly charged. The sensor and transmitter can be integrated within the tool so as to be protected from damage during run in. While in service the sensor and transmitter can monitor pressure in real time and include a capability to send surface signals for real time monitoring of chamber pressures corrected for the service depth, temperature and density of the hydraulic fluid, for example. The signal can be acoustic through the control line or the annulus or delivered through a fiber optic cable or signal wire run in the hydraulic control line, an auxiliary line or through the annulus.Type: GrantFiled: January 7, 2010Date of Patent: May 10, 2011Assignee: Baker Hughes IncorporatedInventors: Darren E. Bane, Steven L. Jennings, David Z Anderson, Steve Rosenblatt

Patent number: 6612547Abstract: Several downhole flow control devices are disclosed which are meterable and are also capable of shutting of a particular zone in a well. The several embodiments include a multiple valve body, a toroidal inflatable valve, and a series of related choke systems. The downhole flow control choke mechanisms each include a downhole electronics package to provide programming or decision making capacity as well as motor actuation systems. Each choke mechanism also includes a system whereby the device can be converted to manual operation and actuated by a conventional shifting tool.Type: GrantFiled: August 28, 2001Date of Patent: September 2, 2003Assignee: Baker Hughes IncorporatedInventors: Michael A.

Publication number: 20030127232Abstract: An apparatus and methods are disclosed for using optical sensors to determine the position of a movable flow control element in a well control tool. A housing has a movable element disposed within such that the element movement controls the flow through the tool. An optical sensing system senses the movement of the element. Optical sensors are employed that use Bragg grating reflections, time domain reflectometry, and line scanning techniques to determine the element position. A surface or downhole processor is used to interpret the sensor signals.Type: ApplicationFiled: November 7, 2002Publication date: July 10, 2003Applicant: Baker Hughes IncorporatedInventors: Terry R. Bussear, Michael A. Carmody, Steven L. Jennings, Don A. Hopmann, Edward J. Zisk, Michael Norris
