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.

Abstract: A method and system can obtain real time property measurements of a fluid comprising a formation fluid downhole, real time measurements of an amount of an interactive component of the fluid downhole, and real time measurements of an amount of a non-interactive component of the fluid downhole. The method and system further includes determining a total amount of the interactive component in the fluid or a contamination level of the formation fluid at a time of interest based on the real time property measurements of the fluid downhole and the real time measurements of the amounts of the interactive component and non-interactive component downhole. The real time measurements of the amount of the interactive component downhole are real time measurements of the amount of the interactive component in its free form downhole, and the property can be scaled with the contamination level.

Abstract: The present invention addresses to a method for analyzing and detecting solids in emulsions, oil and derivatives thereof even in the presence of high contents of water (>5% v/v), which is based on the absorption and scattering of light by solids suspended in solution. The application of the method of this invention contributes to greater reliability in terms of control of BSW (oil quality) and OGC (water to be treated and discarded). Additionally, there is the possibility of controlling the dosage of products such as scale inhibitors and naphthenates inhibitors, optimizing the dosage and minimizing operational occurrences associated with the formation of deposits. These eventually lead to equipment clogging throughout the process.
