Patent number: 8881833Abstract: An apparatus for use downhole is disclosed that, in one configuration includes a downhole tool configured to operate in an active position and an inactive position and an actuation device, which may include a control unit. The apparatus includes a telemetry unit that sends a first pattern recognition signal to the control unit to move the tool into the active position and a second pattern recognition signal to move the tool into the inactive position. The apparatus may be used for drilling a subterranean formation and include a tubular body and one or more extendable features, each positionally coupled to a track of the tubular body, and a drilling fluid flow path extending through a bore of the tubular body for conducting drilling fluid therethrough. A push sleeve is disposed within the tubular body and coupled to the one or more features.Type: GrantFiled: September 30, 2010Date of Patent: November 11, 2014Assignee: Baker Hughes IncorporatedInventors: Steven R. Radford, Khoi Q. Trinh, Jason R. Habernal, R. Keith Glasgow, Jr., John G. Evans, Bruce Stauffer, Johannes Witte

Publication number: 20130058187Abstract: An apparatus for agitating materials contained in tubes, including cellular materials and tissues, to release their contents for scientific analysis. The apparatus includes a control enclosure containing a base and a motor, and an interchangeable module that connects to the motor. The interchangeable module includes a tube supporting structure and a rotatable hub connected to one or more strikers positioned to impact the tubes, resulting in agitation of tube contents. Interchangeable modules allow for different shapes and sizes of tubes to be used with a single control enclosure. The apparatus includes a means to measure the rotational velocity of the rotatable hub and a method for using the speed to determine the number of tubes in the apparatus, or the mass or volume of samples contained in tubes.Type: ApplicationFiled: September 6, 2011Publication date: March 7, 2013Inventors: Brendan George Hart, Ian Keith Glasgow, David Grinnell

Patent number: 8100196Abstract: Drill bits and methods for sampling sensor data associated with a state of a drill bit are disclosed. A drill bit for drilling a subterranean formation comprises a bit configured for receiving a data analysis module. The data analysis module comprises at least one sensor, a memory, and a processor. The processor is configured for executing computer instructions to filter information derived from sensor data in the drill bit to develop a piecewise polynomial curve of the sensor data. Filtering information derived from the sensor data comprises approximating a first derivative of a sensor data waveform, calculating a plurality of zeros for the first derivative of the sensor data waveform, and fitting a cubic polynomial between adjacent zeros calculated from the first derivative of the sensor data waveform resulting in a piecewise cubic polynomial.Type: GrantFiled: February 6, 2009Date of Patent: January 24, 2012Assignee: Baker Hughes IncorporatedInventors: Paul E. Pastusek, Eric C. Sullivan, Daryl L. Pritchard, Keith Glasgow, Tu Tien Trinh, Paul J. Lutes

Patent number: 7987925Abstract: Drill bits and methods for sampling sensor data associated with the state of a drill bit are disclosed. A drill bit for drilling a subterranean formation comprises a bit body and a shank. The shank further includes a central bore formed through an inside diameter of the shank and configured for receiving a data analysis module. The data analysis module comprises a plurality of sensors, a memory, and a processor. The processor is configured for executing computer instructions to collect the sensor data by sampling the plurality of sensors, analyze the sensor data to develop a severity index, compare the sensor data to at least one adaptive threshold, and modify a data-sampling mode responsive to the comparison. A method comprises collecting sensor data by sampling a plurality of physical parameters associated with a drill bit state while in various sampling modes and transitioning between those sampling modes.Type: GrantFiled: October 8, 2010Date of Patent: August 2, 2011Assignee: Baker Hughes IncorporatedInventors: Paul E.
