Utilizing fluid phase behavior interpretation to increase sensor measurement information accuracy
First Claim
1. A method for utilizing fluid phase behavior interpretation to increase sensor measurement information accuracy, said method comprising:
- measuring, by a downhole sensor, detector responses within a measurement sample of a downhole fluid;
acquiring the measured detector responses from the downhole sensor;
generating a correlation factor as a scalar product between a vector of the measured detector responses and a vector of known responses, wherein 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;
comparing the correlation factor to a correlation threshold for a specified material; and
identifying sets of data having correlation factors greater than the correlation threshold.

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.
