The rotational angles showed a mean inaccuracy of 10 degrees, which was mostly due to constraints in the segmentation model's...

... surface, which improves cuttings removal and rock-failing efficiency. The surface-shaped profile on the FRS also led to a 35% reduction in frictional losses. FPE showed a 30% reduction in vertical force and rate of penetration (ROP) improvements compared to a typical round and planar PDC geometry due...

... in a growing wellbore was created based on a drift-flux model. It incorporates three key features. First, a dynamic, real-time meshing method appends new calculation cells to the bottomhole location as the well is deepened. Second, geometry and drilling fluid physical properties near the interfaces between...
