  • Method for Transmission of Data from a Downhole Sensor Array
    Publication number: 20130234859
    Abstract: A method for transmission of data from a downhole sensor array. A continuous unidirectional data stream is sent from the downhole sensor array to two or more different types of data transmitters at the same time. One or more of the two or more different types of data transmitters is then activated to transmit the data from the downhole sensor array.

  • System for drilling deviated boreholes
    Patent number: 5602541
    Abstract: Improved techniques are provided for drilling a deviated borehole through earth formations utilizing a rotary bit powered by a drill motor, and for obtaining information regarding the borehole or earth formations. A sensor permanently positioned in the drilling string between the drill bit and the drill motor detects a downhole parameter. An MWD tool may be provided within a non-magnetic portion of the drill string for receiving and transmitting a sensor representative signal to the surface. The sensor signal allows the drilling operation to be altered, and highly reliable and near-bit information thus improves the drilling operation.

  • System for drilling deviated boreholes
    Patent number: 5163521
    Abstract: Improved techniques are provided for drilling a deviated borehole through earth formations utilizing a rotary bit powered by a drill motor, and for obtaining information regarding the borehole or earth formations while drilling. An inclinometer is positioned below the drill motor and within a sealed cavity of a housing fixed to a drill motor sub, and a transmitter within the sealed cavity forwards acoustic or radial wave signals to a receiver provided in a measurement-while-drilling tool. The MWD tool may be provided within a non-magnetic portion of the drill string, and further houses an accelerometer for sensing borehole direction. Both borehole inclination and directional signals are transmitted to the surface by the MWD tool, and the drilling trajectory is altered in response to the signals.
