Abstract: Horizontal directional drilling (HDD) is a trenchless technology used to install underground utilities. The force required to pull a pipe through the borehole during installation is crucial to design engineers. Various ...

Abstract: In horizontal directional drilling (HDD), accurate determination of the pullback force for pipe installation (pullback) during the design phase is critical to the success of the project. For the calculation of pullback ...

Abstract: Hole cleaning is a significant issue in well drilling, and this problem becomes more severe in horizontal directional drilling (HDD). One of the main functions of the drilling fluid is to transport cuttings from the borehole ...
