The gelling of waxy crudes and the deposition of wax on the inner walls of subsea crude oil
pipelines present a costly problem in the production and transportation of oil. The timely …

Wax deposition and gel formation have been crucial problems to the oil industries. The
deposition of waxes would lead to gelation which blocks flow in pipelines and interrupts …

Yield stress fluid flows occur in a great many operations and unit processes within the oil
and gas industry. This paper reviews this usage within reservoir flows of heavy oil, drilling …

The areas of suspension mechanics, stability and computational rheology have exploded in
scope and substance in the last decade. The present book is one of the first of a …

Many drilling muds and crude oils are known to be thixotropic. Under a wide range of
pressures, temperatures and flow regimes, they display unusual complex flow properties …

Predicting an accurate startup pressure for gelled waxy crude oils in pipelines is an old
challenge yet to be overcome. It is known that the conventional force balance grossly …

We investigate the problem of the start up of a compressible flow in a pipeline filled with a
viscoplastic and thixotropic material. The objective of this study is to examine the possibility …

An experimental study of the flow of yield stress materials was conducted. The main goal
was to understand the relationship between the minimum axial pressure gradient required …

In the seven years since the first edition appeared, several significant additions to model the
flows of viscoplastic fluids have occurred. In this volume, these novel aspects are …

We present results of a primarily experimental study of buoyant miscible displacement flows
of a yield stress fluid by a higher density Newtonian fluid along a long pipe, inclined at …
