Direct measurement of fluid contamination

摘要

The present disclosure relates to apparatuses and methods to detect a fluid contamination level of a fluid sample. The method may comprise providing a fluid sample downhole from a subterranean formation, applying a reactant to the fluid sample to create a combined fluid, observing the combined fluid, and determining if contaminants are present within the fluid sample based upon the observing the combined fluid.

1. A method, comprising: providing a fluid sample from downhole reservoir fluid extracted from a subterranean formation; applying a reactant to the fluid sample to create a chemical reaction at a downhole wellbore location within a downhole fluid sampling tool, wherein the reactant comprises a substance, chemical, or compound that is known to react with olefin; observing the chemical reaction at the downhole wellbore location; and determining if drilling fluids are present within the fluid sample in the downhole sampling tool based on the observation of the chemical reaction at the downhole wellbore location, wherein the drilling fluids are fluids pumped to the downhole wellbore location from the Earth's surface.
