Abstract: Data transmission from a bottom hole assembly (BHA) includes obtaining a scan from multiple scans forming a downhole data log of a borehole within a subterranean formation. The scan includes a sequence of data items from a sensor in the BHA located in the borehole. Each data item corresponds to an azimuth angle of the sensor. Further, compressed scan data is generated from the sequence of data items on a per-scan basis, and transmitted, using a pre-determined borehole telemetry, to a surface unit.

Abstract: A well-logging system may include a tool assembly to be positioned within a borehole of a subterranean formation and to store second data including a second time marker related to a first time marker. The well-logging system may include a controller above the subterranean formation. The controller may process first data including the first time marker, recover the second data, and synchronize the second data based upon the second time marker and the first time marker.

Abstract: Devices, systems and methods for transmitting downhole data are provided. The devices include a rotor-stator modulator configured for use in a drill string, and a drive and control system configured to drive the rotor according to a modulation scheme resulting in both oscillating and full rotational movement. The modulation scheme can comprise a trajectory algorithm such as a QAM trajectory algorithm. The systems include a modulator disposed within a drill string which creates modulated pulses according to an algorithm providing for both oscillating and full rotational movement of the rotor, and may also include a demodulator. The methods include transmitting coded data by driving a rotor relative a stator disposed in a drill string according to a modulation scheme that provides both oscillating and full rotational movement and results in modulated mud pulses representative of data recorded downhole, and may involve decoding the data.

Abstract: A technique facilitates diagnosis of a telemetry system, such as a mud pulse telemetry system or an electro-magnetic telemetry system. The technique comprises operating a telemetry system in a wellbore and collecting a variety of data. The data may relate to a rig state, a downhole state, a signal state, a surface state, and/or other suitable types of data. The data is processed to determine whether states of operation indicated by the data match states indicating a problem with operation of the telemetry system. If a problem is detected, appropriate information regarding the problem is transmitted for use in correcting the problem.
