Primary cementing of horizontal wells. Displacement flows in eccentric horizontal annuli. Part 1. Experiments
Alondra Renteria,Ian Frigaard +1 more
TL;DR: In this paper, the authors present results of 300 miscible Newtonian displacement flow experiments carried out in a dimensionally scaled laboratory set-up and show that dispersive effects dominate to the extent that the slumping flows are best described by bulk diffusive spreading of the height-averaged concentrations, relative to the mean flow.
Neutrally buoyant miscible jets into viscoplastic ambient fluids
TL;DR: Experimental study of neutrally buoyant miscible jets into viscoplastic fluids reveals four distinct flow patterns: mixing, mushroom, fingering, and fracturing regimes, influenced by yield stress and jet inertia ratio, with implications for oil and gas well cleaning operations.
Inline motion and hydrodynamic interaction of 2D particles in a viscoplastic fluid
TL;DR: In this paper, the authors address the case of having multiple particles and introduce interesting new phenomena, such as plug regions can appear between the particles and connect them together, depending on the proximity and yield number.

TL;DR: In this article, it is shown that for certain combinations of the physical properties, there will be a steady state displacement front and that the wide and narrow sides of the front advance at the same speed.
Flow, onset and stability: Qualitative analysis of yield stress fluid flow in enclosures
Ida Karimfazli,Ian Frigaard +1 more
TL;DR: In this article, the main dynamic features and illustrate how they depend upon the applied force, yield stress and purely viscous forces, for two classes of flows, for which the body force is coupled with the flow field, taking natural convection as an example.
