Bridge sensor design for water and oil analysis in formation testing

Abstract

A downhole fluid sampling tool may include an optical measurement tool and a viewing region disposed in the optical measurement tool. In examples, a bridge may be disposed in a transparent portion of the flow path between a light source and a light modifier and an optical detector. The bridge includes a structure comprising a substrate and a contrast agent, wherein the contrast agent is any molecule configured to interact with an analyte and alter a property of the analyte and/or contrast agent, wherein the property is detectable by the optical measurement tool.
