Patent number: 9431813Abstract: A system and method for providing redundant wired pipe-in-pipe telemetry is described. The redundant wired pip-in-pipe telemetry system includes an outer pipe and an inner pipe disposed within the outer pipe. Within the outer pipe, two or more conductive elements may be provided as well as a wired path controller that may selectably switch between available conductive paths. The wired path controller may identify conductive paths with good electrical characteristics and select those paths for transmission. If a conductive path develops a fault, the wired path controller may select one of the alternative redundant conductive paths for transmission to avoid the fault. The wireless controller may further transmit information about the location of faults to a drill operator at the surface.Type: GrantFiled: March 11, 2013Date of Patent: August 30, 2016Assignee: Halliburton Energy Services, Inc.Inventors: Clive D.

Patent number: 9010461Abstract: A managed bulk drilling system that employs a guide wire for ranging and crosswell telemetry. Some system embodiments include multiple drilling assemblies operating in the vicinity of a reference well that contains an electrical cable. The electrical cable is coupled to a surface control system. The control system uses the electrical cable as part of an antenna to receive uplink signals from the drilling assemblies and to broadcast down-link signals to the drilling assemblies. The uplink signals can include position data and the downlink signals can include individual steering commands to adjust the trajectories of each drilling assembly. The cable can also generate a guidance field for the drilling assemblies to detect and follow.Type: GrantFiled: June 1, 2009Date of Patent: April 21, 2015Assignee: Halliburton Energy Services, Inc.Inventor: Richard T.

Patent number: 8912915Abstract: A borehole array for ranging and crosswell telemetry is disclosed along with certain methods for employing such a borehole array. Some embodiments of the borehole array include electrically coupled reference nodes distributed along the length of a reference well. Each reference node includes a solenoid operated by a control unit. The control unit employs the solenoid to generate a magnetic field for guiding a bottomhole assembly in a nearby well. The control unit further serves as a communications intermediary between the bottomhole assembly and a surface facility. The bottomhole assembly can be guided in turn by subsequent reference nodes of the array and employ the closest reference node as a communications link to the surface. Moreover, the use of multiple reference nodes offers greater precision in determining the bottomhole assembly's position relative to the reference well. The borehole array can be used to guide multiple drilling operations concurrently.Type: GrantFiled: July 2, 2009Date of Patent: December 16, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Richard T.

Publication number: 20140340520Abstract: Systems and tools for detecting the presence of a substance of interest is presented. The system utilizes a hyperspectral imaging camera to obtain images of an enclosed area, such as a vehicle. Vehicles can include cars, trucks, trains, or boats. The system also includes a processor and storage device. The processor receives the images taken by the hyperspectral imaging camera. Next, the processor determines whether such images contain certain substances. These substances include alcohol, carbon monoxide, illegal substances, and hazardous chemicals. The storage device is electrically coupled to the processor, and is used to store certain data information such as detection events, substance detected, and the time of detection. Such information can be sent over the internet, or streamed live to a laptop at a remote location. The present embodiment can be used by law enforcement to monitor vehicles of interest, and become an important part of public safety.Type: ApplicationFiled: September 20, 2011Publication date: November 20, 2014Applicant: HALLIBURTON ENERGY SERVICES INC.Inventor: Richard T.

Publication number: 20140190747Abstract: A system and method for automatic weight-on-bit sensor calibration is described. Embodiments of the invention automatically compensate the measurements of a weight-on-bit sensor based on one or more of mass, hole inclination, buoyancy, drag, and mud flow, resulting in a more accurate axial force measurement below the weight-on-bit sensor at various hole inclinations. This measurement is observed by removing some of the effects masking the actual force being applied to the axial face of the drill bit.Type: ApplicationFiled: June 29, 2011Publication date: July 10, 2014Applicant: HALLIBURTON ENERGY SERVICES INC.Inventor: Richard T.
