Increasing cuttings bed height is a serious concern during extended-reach well drilling. In
order to predict and prevent cuttings bed height increase, it is essential to study how the …

Cuttings transport is a topic of great interest in the oil and gas drilling industry. Insufficient
cuttings transport leads to several expensive problems. Knowledge and selection of the …

Drillpipe eccentricity is a common issue in horizontal drilling operations. The eccentricity is a
non-manipulative parameter by itself but its impact is a function of various parameters such …

An experimental study followed by comprehensive flow modeling is presented. The
experiments were conducted on a horizontal annulus with drillstring under compression …

Experimental measurements of the pressure losses in a well annulus are costly and time
consuming. Pressure loss calculations in annulus is generally conducted based on an …

A thorough understanding and accurate prediction of non-Newtonian fluid flow dynamics in
rotating annular media are of paramount importance to numerous engineering applications …

The cuttings transport was numerically simulated based on kinetic theory of granular flow in
combination with sliding mesh for drill pipe rotation in the horizontal well. The Herschel …

Hole cleaning and cuttings transport play a vital role in the drilling operation. Various drilling
problems such as a reduction in penetration rate, an increase in the torque and drag, and an …

Numerical simulations of non-Newtonian fluids are indispensable for optimization and
monitoring of several industrial processes such as crude oil transportation, nuclear cooling …

In rotary drilling, a drillstring is an assembly of slender pipes. It is used to transmit the driving
torque of a motor at the drilling surface to the drill bit at the bottom hole of a 3D well …
