  • Wireless communication between downhole components and surface systems
    Patent number: 11236606
    Abstract: An embodiment of a communication system for communicating between a wired pipe string in a borehole and a surface location includes at least a first wired pipe downhole component and a second wired pipe downhole component in the wired pipe string, a coupler configured to transmit a transmission signal between the first wired pipe downhole component and the second wired pipe downhole component, and a wireless transmission assembly in at least one of the first wired pipe downhole component and the second wired pipe downhole component. The wireless transmission assembly is configured to wirelessly transmit a wireless transmission signal to a receiver antenna, and the receiver antenna is disposed at the surface location and configured to receive the wireless transmission signal.

  • Multi-resolution borehole profiling
    Patent number: 7966874
    Abstract: Harmonics and subharmonics of acoustic measurements made during rotation of a sensor on a downhole are processed to estimate the location of the imager, and size and shape of the borehole. A piecewise elliptical fitting procedure may be used. These estimates may be used to correct measurements made by a standoff-sensitive formation evaluation sensor such as a neutron porosity tool.

  • High resolution gamma measurements and imaging
    Patent number: 7544928
    Abstract: A method for measuring radiation in a borehole, the method including placing a detector comprising a scintillator and a plurality of photodetectors in the borehole; detecting a radiation interaction with a first photodetector; detecting the radiation interaction with at least a second photodetector; and determining a location of the interaction from the detecting; wherein the location provides information regarding formations surrounding the borehole.
