... on cutting transport. Furthermore, it was observed that both (30%) eccentricity and inclination (80–85 °) cause a reduction in cutting volume fraction. Therefore, this study will provide an avenue for the industrial implementation of in situ ERT measurement technology in directional drilling operations...

... mechanism in a horizontal annulus section. A 6.16 m long and 4.5 x2.5 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 fluid was used as drilling mud and 2-3 mm solid glass beds were used...
