Hole cleaning and hydraulics with field fluids are different than the properties considered with most model fluids. Furthermore, results from...

...-phase flow equations for cuttings transport with advanced data-driven and machine learning models in a non-intrusive way. We also demonstrate how data-driven modeling can enhance the accuracy of a physic-based model and vice versa in the context of drilling operations with actual data. We also...

... to cuttings accumulation. Cuttings transport is a complex process that is influenced by drilling parameters such as flow rate, pipe rotation speed, fluid rheology, cuttings properties, and wellbore and drillpipe geometry. Numerous research projects have been conducted to study cuttings transport both using...

... Abstract Cuttings transport is one significant challenge during drilling especially in high deviated and horizontal wellbores. At high degree of inclination, cutting particles may settle to the low side of the wellbore. Below a threshold flow rate, the fluid forces on a particle at the wall...

..., models should enable real-time evaluation of cuttings transport. This work presents a pragmatic transient one-dimensional model of cuttings transport in the annular section. The model is based on a coupling of the drift-flux model with a two-layer approach. The one-dimensional implementation presented...

... Abstract A fundamental understanding of the impact of different hydrodynamic, scaling, and geometric conditions on cuttings transport are essential for successful wellbore drilling. This study presents a validated computational fluid dynamics (CFD) model for investigating cuttings transport...

... horizontal sections, and 3D complex trajectories. Cuttings transport is one of the most challenging problems while drilling such wells, especially at mid-range inclinations. For many years, numerous studies have been conducted to address modeling of cuttings transport, estimation of the concentration...

... with visualization techniques. This study investigates the cuttings transport mechanism in a horizontal annulus section. A 6.16 m long and 4.5″ × 2.5″ annulus section was used to model the real-time drilling behaviour with different flow rates, drill pipe rotations and eccentric positions. Water as a Newtonian...

... Abstract As explorations advance and drilling techniques become more innovative, complex and challenging trajectories arise. In consequence, cuttings transport has continued to be a subject of interest because, if the drilled cuttings cannot be removed from the wellbore, drilling cannot proceed...

... cleaning in wells with long deviated sections is complicated and a transient approach is required to fully understand the hole-cleaning condition. Effective hole cleaning does not only mean that the cuttings concentration is low or the cuttings transport ratio is high. In addition, the absence...
