In this paper, we present a comprehensive review of the methods used for the rheological
characterization of the yield-power-law (YPL) fluids. Ten different rheological …

An evaluation is presented of the practical usage of the Herschel-Bulkley viscosity model for
drilling fluids. If data from automatic viscosity measurements exist, the parameters should be …

Accurate characterization of the rheological behavior of non-Newtonian fluids is critical in a
wide range of industries as it governs process efficiency, safety, and end-product quality …

During the life cycle of an oil well, the annular cement sheath will be exposed to load
combinations that can result in failure. To enhance the structural integrity and ductility of the …

The accurate and frequent measurement of the drilling fluid's rheological properties is
essential for drilling engineering. To measure drilling fluid's rheological properties …

Water-soluble polymers are becoming increasingly important in various applications, such
as stabilizer fluids and drilling muds. These materials are used as viscosifiers and filtration …

Drilling fluids are designed to be shear-thinning for limiting pressure losses when subjected
to high bulk velocities and yet be sufficiently viscous to transport solid material under low …

The occurrence of barite sag in drilling fluids has relatively often been the cause for gas
kicks in oilwell drilling. The subsequent absorption of gas into drilling fluid could lower the …

A number of different models are used to describe the shear rate dependent viscosity of
drilling fluids. Most, such as the Herschel-Bulkley model, have a purely empirical basis. The …

In this paper, we study non-one-dimensional convective layered flows of a viscous
incompressible fluid with a spatial acceleration. We perform the simulation on the base of …
