    • 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.

    • Apparatus, systems, and methods may operate to discharge a plurality of spike fluids into a fluid flowing in a flow channel, transmit energy to the fluid using an energy source coupled to the flow channel, receive the energy modified by the fluid as photometric energy, convert the photometric energy to at least one photometric signal, compare the at least one photometric signal with a reference signal to determine at least one photometric property of the fluid, and determine at least one component of the fluid using the at least one photometric property supplied to a generalized standard addition method (GSAM). Additional apparatus, systems, and methods, including the use of multivariate curve resolution (MCR) to refine GSAM results, are disclosed.
