This report is an updated version of the original engineering design guide published in 1995 by the Pipeline Research Committee (PRC) of the American Gas Association. As with the original document, it is intended to serve as a step by step guide for…
The objective of the Phase 2 project is to develop a tool that can be coupled with a pipeline drill rig to detect pipeline obstacles in the drill path. This project is also referred to as Differential Impedance Obstacle Detection. The physical size…
Directional drilling technology as related to the installation of small and large diameter pipelines at water crossings is continually improving. The current technology provides pipeline owner/operators with a valid installation option for both…
Technical references and papers used to generate report 'L51725 Drilling Fluids in Pipeline Installation by Horizontal Directional Drilling-A Practical Applications Manual'.
Construction contractors often claim extra compensation associated with horizontally directionally drilled (HDD) pipeline installations is needed when drilling in rock. These claims result from HDD contractors' allegations that rock properties…
Drilling fluid plays a key role in the installation of a pipeline by horizontal directional drilling (HDD) and accounts for the majority of the associated environmental impact. An improper drilling fluid program can result in stuck pipe. Uncontrolled…
Approximately 100 citations and 50 U.S. patents were identified on the subject of HDD in permafrost environments, through 12 databases.The search was not limited by date or by language, in order to get a broadly based output.
Despite the advances that have been made in the horizontal directional drilling (HDD) industry over the past 40 years, damage to existing underground facilities as a result of HDD operations remains a serious concern. HDD poses a unique risk of…
The objectives of the research are to develop guidelines for installing pipelines beneath rivers and within levee right-of-way using HDD techniques, without endangering the levees, and to demonstrate that these techniques offer substantial economic…
