Abstract
Various embodiments include apparatus and methods to utilize fluid phase behavior interpretation to increase sensor measurement accuracy. In some embodiments, a downhole sensor measures detector responses within a measurement sample of a downhole fluid. The measured detector responses are acquired from the downhole sensor. A correlation factor is generated as a scalar product between a vector of the measured detector responses and a vector of known responses. The correlation factor has a value within a fixed interval, one end of the fixed interval corresponding to a high correlation status and an opposite end of the fixed interval corresponding to an uncorrelated status. The correlation factor is compared to a correlation threshold for a specified material and sets of data having correlation factors greater than the correlation threshold are identified.
