Abstract: Disclosed are methods and systems for determination of fluid contamination of a fluid sample from a downhole fluid sampling tool. A method may comprise obtaining a fluid sample, wherein the fluid sample comprises a reservoir fluid contaminated with a well fluid; obtaining input parameters, wherein the input parameters comprise fluid properties obtained from measurement of the fluid sample and mud filtrate composition; obtaining initial values of iterative parameters, wherein the iterative parameters comprise fluid contamination of the fluid sample; determining component mole fractions of the reservoir fluid using the initial values of the iterative parameters in a mole fraction distribution function; determining calculated fluid properties of the reservoir fluid using equation of state flash calculating; and repeating steps of determining component mole fractions and determining calculated fluid properties and further obtaining updated values of the iterative parameters for use in the mole fraction distribution function until a comparison of one or more of the calculated fluid properties with one or more of the input parameters is within a tolerance error.

Abstract: Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof.

Abstract: Apparatus, systems, and methods may operate to select a subset of sensor responses as inputs to each of a plurality of pre-calibrated models in predicting each of a plurality of formation fluid properties. The sensor responses are obtained and pre-processed from a downhole measurement tool. Each of the plurality of predicted formation fluid properties are evaluated by applying constraints in hydrocarbon concentrations, geo-physics, and/or petro-physics. The selection of sensor responses and the associated models from a pre-constructed model base or a candidate pool are adjusted and reprocessed to validate model selection.
