Abstract:

Knowledge of oilfield reservoir fluid properties is necessary for petroleum exploration as it enables one to determine which hydrocarbons are economically viable to exploit. Downhole measurements are challenging due to the high pressures, high temperatures, and space limitations on tools conveyed downhole. Microfluidics and microsensors offer the means of measuring the fundamental properties of fluids without the need for large volumes of formation fluids. This presentation will review recent progress of Schlumberger-Doll research in the field of microfluidics, including microsensors that measure fluid density, viscosity, composition, and saturation pressures in an extremely challenging environment.
