Abstract: An apparatus for measuring a viscosity of a fluid is disclosed. The apparatus includes a Parylene coated quartz tuning fork for immersion in the fluid and an electronic circuit to excite a vibration of the Parylene coated quartz tuning fork and measure one or more vibrational parameters of the Parylene coated quartz tuning fork. A computer processor is configured to determine a non-Newtonian viscosity from the vibration of the Parylene coated quartz tuning fork based, at least in part, on a Stokes flow hydrodynamic model. The computer processor is coupled to a memory for storing a calibration curve to determine a Newtonian viscosity of the fluid from the non-Newtonian viscosity of the fluid.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including performing, using a nanoscale model, a simulation of fluid-fluid and fluid-rock interactions in the subterranean formation. The operations also include upscaling first results of the simulation of fluid-fluid and fluid-rock interactions to a microscale level. The operations further include performing, using a microscale model and the upscaled first results, a simulation of fluid flow inside rocks of the subterranean formation. Additionally, the operations include upscaling second results of the simulation of fluid flow inside rocks to a macroscale level. Further, the operations include performing, using a core-scale model and the upscaled second results, a simulation of fluid flow across the subterranean formation.
