  • Exploitation of sea floor rig structures to enhance measurement while drilling telemetry data
    Patent number: 9234981
    Abstract: A method for communicating data in an offshore data communication system comprises measuring L/MWD data with a sensor disposed in a bottomhole assembly positioned in a subsea borehole. The bottomhole assembly is disposed along a drillstring extending through the subsea borehole. In addition, the method comprises communicating the L/MWD data from the bottomhole assembly to the seafloor with a telemetry signal. Further, the method comprises receiving the telemetry signal with at least one telemetry transducer positioned proximal the sea floor. Still further, the method comprises processing the telemetry signal at the seafloor to produce a processed signal. Moreover, the method comprises transmitting the processed signal from the sea floor to the sea surface.

  • Communication via fluid pressure modulation
    Patent number: 8339277
    Abstract: In some embodiments, an apparatus [100] and a system, as well as a method and an article, may operate to transmit downhole data in a drilling fluid via fluid pressure modulation, and receive the downhole data at a fluid pulse receiver included in a conduit [104] coupled to a drill pipe downstream from a Kelly hose. Other apparatus, systems, and methods are disclosed.
