  author={Ali Karimi Vajargah and Gregory Sullivan and Mitchell Johnson and E. D. van Oort},
Precise prediction of frictional pressure loss of drilling fluids, which usually exhibit non-Newtonian behavior, plays a vital role in drilling hydraulics. A transitional or turbulent flow regime is often anticipated in the drillstring during drilling/circulating operations. Semi-analytical solutions that are extensively used in the industry rely on empirical correlations to predict the frictional pressure loss in transitional or turbulent flow. However, this approach has been proven to be…

Comparing a Basic Set of Drilling Fluid Pressure-Loss Relationships to Flow-Loop and Field Data

This paper is an extension of a recent AADE publication that introduced the Unified model as a practical rheological characterization of Herschel-Bulkley fluids. Equations have been added to handle

Determination of turbulent pressure loss of non-newtonian oil flow in rough pipes

SummaryA detailed theoretical analysis is carried out of the turbulent flow of non-newtonian fluids in rough pipes in which approximate assumptions are of negligible importance. A new friction-factor

Transition Criteria for Laminar to Turbulent Flow for Yield Power Law (YPL) Fluids Based on Stability Analysis

It is well known that a Newtonian fluid with the presence of solid particles in suspension behaves non-Newtonian. Higher the solid content, more significant the yield stress of the fluid.

Correlations predict friction pressures of fracturing gels

Friction pressure calculations are very important in the design of any hydraulic fracturing treatment. They are useful in determining horsepower requirements, bottomhole treating pressure, and

Laminar-Turbulent Transition in Flow of Pseudoplastic Fluids with Yield Stresses

An analysis of the laminar-turbulent transition behavior of power law non-Newtonian fluids with yield stresses reveals that considerable interaction occurs between the characterizing parameters m and

Turbulent flow of non‐newtonian systems

A theoretical analysis for turbulent flow of non-Newtonian fluids through smooth round tubes has been performed for the first time and has yielded a completely new concept of the attending
