    Abstract: A frequency sensor comprises a surface functionalized with a reactant sensitive to an analyte and a vibration detector coupled to the functional surface to detect a frequency of a fluid having the analyte and located on the functional surface during vibration thereof. The frequency sensor comprises a measurement circuitry coupled to the vibration detector to determine a frequency shift over time of the detected frequency, wherein the frequency shift corresponds to the presence of the analyte which has reacted with the reactant.

    Abstract: Systems, tools, and methods are presented for processing a plurality of spectral ranges from an electromagnetic radiation that has been interacted with a fluid. Each spectral range within the plurality corresponds to a property of the fluid or a constituent therein. In one instance, a series of spectral analyzers, each including an integrated computational element coupled to an optical transducer, forms a monolithic structure to receive interacted electromagnetic radiation from the fluid. Each spectral analyzer is configured to process one of the plurality of spectral ranges. The series is ordered so spectral ranges are processed progressively from shortest wavelengths to longest wavelengths as interacted electromagnetic radiation propagates therethrough. Other systems, tools, and methods are presented.

    Abstract: The disclosed embodiments include a method, apparatus, and computer program product for determining a synthetic gas-oil-ratio for a gas dominant fluid. For example, one disclosed embodiment includes a system that includes at least one processor, and at least one memory coupled to the at least one processor and storing instructions that when executed by the at least one processor performs operations that include optimizing a gas-oil-ratio database using a genetic algorithm and a multivariate regression simulator and generating a synthetic gas-oil-ratio for a gas dominant fluid. In one embodiment, optimizing a gas-oil-ratio database using a genetic algorithm and a multivariate regression simulator comprises defining gas-oil-ratio searching boundaries gas-oil-ratio for each gas dominant fluid; assigning randomly a synthetic gas-oil-ratio for each gas dominant fluid in a set of gas dominant fluids in the initial population of gas-oil-ratio data, wherein the gas-oil-ratio for each gas dominant fluid is within the searching boundaries; generating an initial population of gas-oil-ratio data for a set of gas dominant fluids; and evaluating synthetic gas-oil-ratio assignments for the initial population using the multivariate regression simulator.
