    Abstract: A downhole compressible fluid sampling tool includes a primary fluid flow line deployed between a fluid inlet probe and a fluid outlet line. A fluid analysis module and a fluid pumping module are deployed in the primary fluid flow line. The fluid pumping module includes a pump in parallel with a bypass flow line having a bypass valve. A compressible fluid sampling vessel is deployed in parallel with and in fluid communication with the primary flow line. A method for obtaining a sample of a compressible downhole fluid includes turning off the pump and opening the bypass valve to enable the downhole fluid to flow into the fluid sampling vessel. The pump may then be optionally turned back on to pressurize the sample.

    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.
