  • Patent number: 9854551
    Abstract: A linear wireless sensor network includes network nodes having monotonically varying network node identifiers along each branch of the network. The network identifiers enable the nodes to forward network packets without use of routing tables. Low duty cycle wireless communication protocols enable network packets to be routed to all nodes of very large networks while consuming very little electrical power. Broadcast, rather than unicast, transmissions between nodes take advantage of favorable signal propagation conditions to forward messages using largest possible hops, skipping over nodes when possible, as well as automatically adapting to time- or spatially-varying conditions. A group of network packets is broadcast and forwarded by a most distant receiving node that received all packets of the group. A receiving node's clock is automatically adjusted, based on which packet(s) of a group of packets was received. A sending node synchronizes near-by receiving nodes.

  • Patent number: 8994550
    Abstract: A method and system are presented for transmitting data along tubing in a borehole, comprising generating an acoustic signal using a transmitter at a first location on the tubing, and receiving the acoustic signal at a receiver at a second location on the tubing. The method and system further comprise: (i) generating the acoustic signal at the transmitter at a first frequency and bit rate; (ii) receiving the acoustic signal at the first frequency at the receiver and attempting to synchronize the receiver at the first frequency, and (iiia) if the synchronization is successful, continuing to transmit the acoustic signal so as to pass the data from the transmitter to the receiver; or (iiib) if the synchronization is unsuccessful, adjusting the frequency and/or bit rate of the signal and repeating steps (i)-(iii) on the basis of the adjusted signal.

  • Patent number: 8988969
    Abstract: Evaluating utilities involves generating an acoustic or seismic source signal, communicating the source signal to a first underground utility, moving a receiver through a second underground utility situated in proximity to the first utility, and monitoring for a cross bore involving the first and second utilities in response to receiving the source signal emanating from the first utility as the receiver progresses through the second utility. Utility evaluation may further involve detecting a cross bore involving the first and second utilities using monitoring data acquired by the receiver.

  • Patent number: 8982667
    Abstract: A stacked-ring, slow-wave acoustic telemetry isolation system and method for use with tubular assemblies such as drillpipe or production tubing comprising an acoustic wave transmitter, the acoustic isolator behaving such that a “down” wave propagated toward the isolator is reflected back substantially in phase with an “up” wave propagated from the acoustic wave source away from the isolator. The acoustic isolator is similarly effective in reflecting “up” propagating waves originating from below the isolator, hence further protecting the acoustic wave source from possible deleterious interference. It causes substantially all of the emitted wave energy to travel in a chosen direction along the drill pipe, thus aiding the efficiency of acoustic telemetry said pipe.

  • Patent number: 8981957
    Abstract: Remote operation of downhole tools in a subterranean wellbore is performed by inserting untethered, mobile devices sequentially into the wellbore. The mobile devices can include motive means, power supply, communication and data storage means, etc. In one embodiment, the method comprises maneuvering a first mobile device into proximity with a downhole tool, the device powering the tool. The first device is then removed, such as by flowing up or dissolving. The now-powered tool is used to perform a test or other operation. A second mobile device is maneuvered into proximity with the downhole tool and data is transferred. The second device is retrieved with the data or, using on-board logic devices, provides “if-then” commands to the downhole tool. Alternately, a third mobile device can be used to power and transfer commands to the tool. The method can be used for various tasks, such as opening bypass ports on ICD valves.

  • Patent number: 8976017
    Abstract: A method for inspecting down hole drilling systems for identifying indications of flaws in material. The method can include removing particulate, disposing a wave coupling medium on an area of interest, attaching a probe to a sound carrying wedge, engaging the sound carrying wedge over the wave coupling medium, transmitting inspection signals to the area of interest, manipulating the probe to produce detection signals, transmitting the detection signals to a data storage, presenting the detection signals and a known reference level to a user, and comparing the detection signals to the known reference level to determine if the detection signals are within a standard deviation of the known reference level. The method can include adapting a sound carrying wedge to form-fittingly couple to an area of interest of a down hole drilling system.

  • Patent number: 8942330
    Abstract: A method for reducing interference in a received downhole telemetry signal includes: segmenting a received signal; windowing each signal segment; transforming each windowed signal segment into a complex variable domain to generate a plurality of complex variable domain segments with an in-phase component vector I and a quadrature component vector Q; calculating a real amplitude vector A from the I and the Q vectors; filtering interferers in the amplitude vector A for each complex variable domain segment to generate a filtered amplitude vector Ã; recalculating an amplitude of the amplitude vector A using the filtered amplitude vector à to generate an output amplitude vector Â; scaling the I and the Q vectors by a factor Â/A to generate an output in-phase component vector I? and an output quadrature component vector Q?; and transforming I? and Q? into the time domain to provide an interference-reduced output signal in the time domain.
