AUTOMATED DOWNHOLE FLUID CLASSIFICATION USING PRINCIPAL SPECTROSCOPY COMPONENT DATA
First Claim
1. A method of downhole fluid classification, the method comprising:
- obtaining measurements from one or more downhole sensors located along a current section of wellbore within a subsurface formation;
transforming the measurements obtained from the one or more downhole sensors into principal spectroscopy component (PSC) data;
identifying one or more fluid types for the current section of the wellbore within the subsurface formation, based on the PSC data and a fluid classification model; and
refining the fluid classification model for one or more subsequent sections of the wellbore within the subsurface formation, based at least partly on the one or more fluid types identified for the current section of the wellbore.

Abstract
System and methods for downhole fluid classification are provided. Measurements are obtained from one or more downhole sensors located along a current section of wellbore within a subsurface formation. The measurements obtained from the one or more downhole sensors are transformed into principal spectroscopy component (PSC) data. One or more fluid types are identified for the current section of the wellbore within the subsurface formation, based on the PSC data and a fluid classification model. The fluid classification model is refined for one or more subsequent sections of the wellbore within the subsurface formation, based at least partly on the one or more fluid types identified for the current section of the wellbore.
