    摘要: A borehole seismic shuttle tool includes (a) a tool body having a cavity with an opening in the wall of the tool body; (b) an anchoring arm attached to the tool body and operable to anchor the tool body to the borehole wall; (c) a sensor package positioned in the cavity and mounted on resilient mounts which act to urge the sensor package in the direction of the opening, such that when the tool body is anchored to the borehole wall, the sensor package projects part way through the opening and is held against the borehole wall by the action of the resilient mounts. The tool is characterised in that when the tool body is not in contact with the borehole wall, peripheral portions of the sensor package is urged into contact with the tool body wall surrounding the opening.

    摘要: A method and system for azimuth measurements using one or more gyro sensors is disclosed. The method includes acquiring a first data from each of the gyro sensors with an input axis aligned to a first angular orientation and acquiring a second data from each of the gyro sensors with the input axis flipped to a second angular orientation opposite to the first angular orientation. An earth rate component at the first angular orientations is determined based on a difference between the first data and the second data to cancel out bias of each of the gyro sensors. The method may include acquiring a third data of the gyro sensor with the input axis aligned to the same angular orientation as the first angular orientation. An average of the first data and the third data may be used instead of the first data for determining the earth rate component.

    摘要: A fluid analysis system for use downhole comprises an input light signal that is directed through a fluid sample housed in a sample cell. The input light signal may originate from a plurality of light sources. An output light signal from the sample cell is then routed to one or more spectrometers for measurement of the represented wavelengths in the output light signal. The output of the spectrometers is then compared to known values for hydrocarbons typically encountered downhole. This provides insight into the composition of the sample fluid. Additionally, the light from the light sources can be routed directly to the one or more spectrometers to be used in calibration of the system in the high temperature and noise environment downhole.
