Abstract

The disclosed embodiments include a method, apparatus, and computer program product for generating a cross-sensor standardization model. For example, one disclosed embodiment includes a system that includes at least one processor; at least one memory coupled to the at least one processor and storing instructions that when executed by the at least one processor performs operations comprising selecting a representative sensor from a group of sensors comprising at least one of same primary optical elements and similar synthetic optical responses and calibrating a cross-sensor standardization model based on a matched data pair for each sensor in the group of sensors and for the representative sensor. In one embodiment, the at least one memory coupled to the at least one processor and storing instructions that when executed by the at least one processor performs operations further comprises generating the matched data pair, wherein the matched data pair comprises calibration input data and calibration output data.

Description

BACKGROUND OF THE INVENTION

[0001] Various multivariate models are used to predict chemical compositions and other properties of unknown reservoir fluid samples during formation fluid analysis that are based on the measurements of downhole optical tools. The application of pre-calibrated fluid prediction models is tool dependent, often requiring data standardization or transformation to convert measured sensor responses from the tool data space to the calibration data space. The costs associated with fluid prediction model development and management affects how instrument standardization is performed.BRIEF DESCRIPTION OF THE DRAWINGS
