Abstract
A fiber optic sensing tool assembly is deployed in a wellbore that penetrates a hydrocarbon-bearing formation of interest to measure fluid composition and other fluid characteristics. This measurement is implemented by deploying the tool in a region in which there is substantially no fluid flow and by heating the tool through an optical delivery system. Parameters of the fluid are monitored as a function of the heating of the tool to derive information that is indicative of fluid composition and other fluid characteristics.
