  • Patent number: 10208588
    Abstract: In an example implementation, communications between a downhole logging tool and surface computing subsystem can be provided through a cable that includes one or more electrical conductors. To allow multiple channels of data to be transmitted along a single multi-conductor cable, data can be divided into two or more different channels, and each channel of data can be transmitted along the conductors. Due to the length of the cable, the electrical conductors of the cable may be subject to strong capacitive and inductive coupling. As a consequence of this coupling, signals sent downhole along any two arbitrary conductors may be subject to distortion, and can produce significant “crosstalk” on the other conductors. The effects of crosstalk can be reduced in a variety of ways, for example using QR decomposition.

  • 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.

  • Publication number: 20140326449
    Abstract: This disclosure relates to determining optimal parameters for a downhole operation. In a general aspect, a computer-implemented method for managing a downhole operation is described in this disclosure. The method includes receiving a continuous stream of real-time data associated with an ongoing downhole operation at a data ware house. In the meantime, a selection of a downhole parameter is received from a user. Then, with a computing system, the selected downhole parameter is optimized based on a portion of the received stream of data to approach a target value of the selected downhole parameter. The optimized downhole parameter can then be used in the ongoing operation.

  • Patent number: 8792304
    Abstract: A downlinking signal is transmitted downhole from the surface using drilling fluid as the communications medium. The downlinking signal includes at least a synchronization phase and a command phase. The downlinking signal is differentiated upon reception such that attributes of the synchronization phase may be used to determine corresponding attributes of the command phase. Commands may be transmitted downhole while drilling and simultaneously while using mud-pulse telemetry uplinking techniques.

  • Publication number: 20140077964
    Abstract: Apparatus and associated methods may relate to a sensor controller configured to apply predetermined criteria to determine when a parameter value sampled by a sensor module meets the predetermined criteria, and in response to making such a determination, adjust a commanded data rate including an update time period. In an illustrative example, the predetermined criteria may be independently defined for each sensor in a network. In examples with a network of sensors, the sensor controller may dictate sensor module operation at differentiated data rates. In an illustrative example, a sensor controller may communicate with a series of pressure level sensor modules connected to a drilling apparatus in a mud logging application. Upon detection of a pressure level change that exceeds a critical condition as determined through comparison with the predetermined criteria, the sensor controller may increase or decrease a data rate of the respective sensor module, for example.

  • Patent number: 8655104
    Abstract: A method for removing cyclic noise from a borehole image includes transforming the image into the frequency domain using a two-dimensional (2-D) Fourier Transform, removing cyclic noise components from the transformed image, and inverse transforming the image back into the spatial domain using an inverse 2-D Fourier Transform. The cyclic noise component may also be isolated by subtracting the corrected image from the original image or by removing all non-cyclic noise components from the transformed image prior to inverse transforming. Removal of the cyclic noise from a borehole image tends to enable the identification of borehole features and provide for improved accuracy in formation parameter evaluation. Evaluation of the cyclic noise component may also enable the source of the noise to be identified and mitigated.

  • Patent number: 8633830
    Abstract: A system for communication in an oil and gas well, the system including a controller, a first universal wireless adapter (UWA) wirelessly coupled to the controller, where the UWA is coupled to a first field device, a second UWA wirelessly coupled to the controller, where the UWA is coupled to a second field device, where the controller passes a control token among the first and second UWAs based upon communication traffic between the first and second UWA and the first and second field devices respectively. In some embodiments, this control token may be passed between the first and second UWAs depending upon communications between the respective UWAs and their field devices. For example, in the event that communication traffic is greater between the first UWA and the first field device, then the control token is passed to the first UWA.
