The efficient removal of cuttings from all types of wellbore poses a substantial challenge.
Hole cleaning (HC) depends on the physicochemical interplay between wellbore formations …

This article presents a new turbulence closure based on the k-ω SST model for predicting
turbulent flows of Herschel–Bulkley fluids, including Bingham and power-law fluids. The …

Inclined and horizontal wells are prone to the accumulation of drilling cuttings.
Determination of the optimal drilling parameters that facilitate cuttings removal is a key …

Effective cuttings transport has long been a challenge in oil and gas horizontal drilling, and
inadequate wellbore cleaning can result in severe drilling accidents including stuck pipe …

The high efficiency of hole cleaning is essential and critical for drilling horizontal wells. In
this study, the effects of four-lobed drill pipe on drill cuttings transport behaviors are …

Pneumatic conveying theory is applied to the negative pressure sampling for the gas content
determination in coal seams. Herein, we investigated the gas-solid flow in the drill pipe with …
