Calibration module for pooled optical sensors in downhole fluid analysis

A non-transitory, computer readable medium storing commands which, when executed by a processor, cause a computer to:

• select candidate sensors for pooled calibration and thereby obtain pooled sensors;
• determine a multivariate fluid characterization model using virtual sensor responses corresponding to the pooled sensors;
• determine a virtual master kernel standardization model using real sensor responses of the pooled sensors as inputs;
• implement a calibration result that includes the multivariate fluid characterization model and the virtual master kernel standardization model into a processor circuit;
• and
• perform a fluid analysis by using the processor circuit including determining a value of a fluid characteristic by applying, in the processor circuit, the multivariate fluid characterization model to a plurality of virtual sensor responses obtained from a plurality of real sensor responses to the fluid sample, wherein the plurality of virtual sensor responses is obtained from the plurality of real sensor responses using the virtual master kernel standardization model.
