Horizontal directional drilling (HDD) is a widely used trenchless method for underground utility connections. The associated ground settlement triggered by HDD depends on the size, types, and surface texture of pipe, diameter o
3.2. Range calculations The orthogonal design results are analyzed by the range and variance. The range difference reflects the difference between two extremes in a group of data (i.e., the degree of dispersion of a group of data). The range calculation method was used to determine the influ...

Improper hole cleaning leads to the accumulation of drill cuttings in the well annulus and causes many problems such as rotational speed reduction, stuck pipe, circulation loss, and drill bit abrasion especially in horizontal drilling. In this study, computational fluid dynamics (CFD) were used for...

In oil and gas drilling operations, predictions of pressure losses and cuttings concentration in the annulus are very complex due to the combination of interacting drilling parameters. Past studies have proposed many empirical correlations to estimate pr
