Development of an optimised integrated underbalanced drilling strategy for cuttings transport in gas-liquid flow through wellbore annuli.
… which affect the wellbore hydraulics and cuttings transport efficiency during UBD operations. Thus, this study developed a rigorous integrated strategy for maximising the efficiency of UBD for the transport of cuttings in gas-liquid two-phase flow through wellbore annuli. An experimental …

Cuttings transport and hydraulics optimisation for underbalanced drilling (UBD) operations in concentric and eccentric, directional and extended reach wells.
… increased tendency for the settling of drilled cuttings in the wellbore. An accurate prediction of fluid dynamics and cutting transport efficiency is required to achieve an effective pressure-management hole-cleaning operation. In this research, a theoretical, numerical and experimental study …

Stuck pipe prediction in deviated wellbores: a numerical and statistical analysis.
… event. To achieve this, the use of numerical cuttings transport (hole cleaning) models and statistical analysis of real-time drilling data is proposed by this research. Current cuttings transport models are based on unhindered, free settling in the wellbore and do not adequately account for …

Analytical and Numerical Modeling of Mechanical Cleaning Device (MCD) for High Angle Wells
… grooves or blades on their surface, assist in cuttings bed removal by creating turbulence and bringing the cuttings into suspension for removal by the drilling mud. Several of these subs, primarily meant for highly deviated and horizontal wells, are employed in a typical drilling application to …
