Viscosity Equations in Oil and Water Wells

Abstract

The equations of viscosity and acid spending capacity characterize the performance of wellhead solvents and fluids, such as gasoil-water wellhead base fluids, and the types of wettability-altering solvents. This study evaluates the properties and interactions in the reservoir layers by deriving the viscosity equations for both oil and water layers. The results from these equations were then applied for the acid spending capacity and overburden pressure equations to demonstrate their role in the damage calculations (water block type) for different rock types. Focusing on the overburden pressure and water block effects, the study investigates the role of viscous and non-viscous chemicals and fluids in both causing and removing damages in various mineral compositions of the porous media. Finally, introducing these new equations, the study outlines key approaches for analyzing and calculating chemical characteristics and behavior in porous media under high-temperature and high-pressure conditions using field and experimental data as the example.
