    摘要: Downhole fluid typing with pulsed neutron logging. A method comprises obtaining at least one capture gamma count rate at a particular borehole depth, calculating a fluid type indicative response value for the borehole depth, and determining at least one fluid type based on the response value. A system comprises a downhole tool, including a neutron source, at least one gamma detector, and a processor coupled to a memory. The memory stores a program that, when executed by the processor, causes the processor to obtain at least one capture gamma count rate for a particular borehole depth. The processor calculates a fluid type indicative response value for the borehole depth and determines at least one fluid type based on the response value.

    摘要: In various embodiments, apparatus and methods are provided to perform acoustic imaging. An acoustic wave can be acquired at a detector, where the acoustic wave propagates from a target to the detector. The target may be acoustically illuminated to provide the acoustic wave. A signal from the detector in response to acquiring the acoustic wave can be processed in a model such that the processing implements a synthetic acoustic lens to generate an image of the target. Additional apparatus, systems, and methods are disclosed.

    摘要: Various systems and methods for performing optical analysis downhole with an interferogram (a light beam having frequency components with a time variation that identifies those frequency components. The interferogram is produced by introducing an interferometer into the light path, with the two arms of the interferometer having a propagation time difference that varies as a function of time. Before or after the interferometer, the light encounters a material to be analyzed, such as a fluid sample from the formation, a borehole fluid sample, a core sample, or a portion of the borehole wall. The spectral characteristics of the material are imprinted on the light beam and can be readily analyzed by processing electronics that perform a Fourier Transform to obtain the spectrum or that enable a comparison with one or more templates. An interferometer designed to perform well in the hostile environments downhole is expected to enable laboratory-quality measurements.
