Abstract
A method and system may include receiving, via one or more sensors in a wellbore formed in a subsurface formation, measurements of a concentration of an interactive component and a concentration of a non-interactive component in a formation fluid from the subsurface formation, wherein the non-interactive component and the interactive component comprise a component in the formation fluid that is non-interactive and interactive, respectively, with respect to a drilling fluid. The method and system may further include determining a level of contamination from a drilling fluid filtrate that contaminates the formation fluid based on the non-interactive component concentration in the formation fluid and the interactive component concentration in the formation fluid.
