Pipeline Lifting Mechanics Research of Horizontal Directional Drilling
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 During lifting pipeline of horizontal directional drilling (HDD), the rotation angle of pipeline is determined by such parameters as the location of lifting point, axial force, and length of pipeline. The continuous beam theory is used to analyze the mechanical behaviour of pipeline during lifting construction, and the mechanical model of pipeline ...

New perspectives on horizontal to vertical well ratios for site cleanup
Remediation Journal, Volume 30, Issue 1, Page 27-31, Winter 2019., 2019 Abstract Directional drilling has been used for a variety of purposes, including utilities, dewatering, and remedial activities. Using this method for site cleanup versus traditional vertical extraction wells needs to be considered based upon today's remedial challenges. Traditionally, it has been stated that a single horizontal well can substitute for
