Patent number: 8393414Abstract: Specific apparatus and associated methods are described for use in establishing the positions of locating field detectors and a sonde. Two detectors can be located at positions within the region, each being operable in a transmit mode and in a receive mode such that each one of the detectors in the transmit mode is able to transmit a relative locating signal to the other detector for use in determining the relative position of one detector in relation to the other and such that both detectors receive an electromagnetic locating signal from the sonde in the receive mode for use in determining the position of the sonde and the detectors within the region.Type: GrantFiled: September 15, 2011Date of Patent: March 12, 2013Assignee: Merlin Technology Inc.Inventors: Guenter W. Brune, Peter H. Hambling, John E. Mercer, Lloyd A. Moore, Shiu S. Ng, Rudolf Zeller

Patent number: 8393412Abstract: A system and method of closed loop control whereby groupings of surface sonic transmitters disposed along the planned path of a well send sonic wave energy to a downhole sonic receiver (or alternatively a downhole sonic transmitter signalling to grouping of surface sonic receivers) in a manner that facilitates the downhole positioning of the well. Subsequent offset well positioning, relative to the first well, may be achieved in a similar manner.Type: GrantFiled: February 11, 2010Date of Patent: March 12, 2013Assignee: Xact Downhole Telemetry, Inc.Inventors: Paul L. Camwell, John G. McRory, David D. Whalen, James M. Neff

Patent number: 8381838Abstract: A system for directing the drilling of a well at a drill-site includes an instructing unit, an instructed unit, and a central unit. The instructed unit receives drilling instruction from an instructing driller, sends drilling instructions to the central unit, and presents to the instructing driller drilling instructions and instruction confirmations received from the central unit. The instructed unit receives instruction confirmations from an instructed driller, sends instruction confirmations to the central unit, and presents to the instructed driller drilling instructions received from the central unit. The central unit stores and forwards drilling instructions and instruction confirmations to the instructing unit and instructed unit, and generates and stores slide sheet information from the drilling instructions.Type: GrantFiled: December 31, 2009Date of Patent: February 26, 2013Assignee: Pason Systems Corp.Inventors: Nicholas Hutniak, Sergey Khromov, Aaron Eddy, Robert Rodda, Wes Hansen

Publication number: 20130032404Abstract: Pulsed-electric drilling systems can be augmented with multi-component electromagnetic field sensors on the drillstring, at the earth's surface, or in existing boreholes in the vicinity of the planned drilling path. The sensors detect electrical fields and/or magnetic fields caused by the electrical pulses and derive therefrom information of interest including, e.g., spark size and orientation, bit position, at-bit resistivity and permittivity, and tomographically mapped formation structures. The at-bit resistivity measurements can be for anisotropic or isotropic formations, and in the former case, can include vertical and horizontal resistivities and an orientation of the anisotropy axis. The sensors can illustratively include toroids, electrode arrays, tilted coil antennas, magnetic dipole antennas aligned with the tool axes, and magnetometers.Type: ApplicationFiled: August 1, 2012Publication date: February 7, 2013Applicant: Halliburton Energy Services, Inc.Inventors: Burkay DONDERICI, Ronald J.

Publication number: 20130025939Abstract: During a drilling operation, measured data from the drilling operation may be received with a panistic inversion and risk estimate module. The panistic inversion and risk estimate module may generate a plurality of mathematical solutions from a panistic inversion that uses the measured data and one or more earth models. The one or more earth models having various parameters may be selected prior to drilling and/or while the drilling operation occurs. For each solution of the plurality of mathematical solutions generated from the panistic inversion, the panistic inversion and risk estimate module may determine if the measured data exceeds one or more probability risk thresholds associated with the drilling operation. If the measured data exceeds the probability risk threshold associated with the drilling operation, then the panistic inversion and risk estimate module may generate an alert.Type: ApplicationFiled: July 26, 2011Publication date: January 31, 2013Inventors: DENIS HELIOT, Steven F. Crary, Jean Seydoux
