Horizontal Directional Drilling Installation of Polyethylene Pipe

Pipeline Engineering and Construction, 2004
Horizontal directional drilling (HDD) is a frequently used option for installing polyethylene (PE) pipes for subaqueous crossings, for wetland crossings, and for municipal pipelines in crowded urban and suburban areas. While many consider HHD an "art", there are engineering principles that apply and if followed will result in reliable designs.

Horizontal Directional Drilling with Ductile Iron Pipe

Pipelines 2007, 2007
Since its development in 1948, and its introduction by the industry in 1955, Ductile Iron Pipe has become the most widely used product for water line installations. In conjunction with water line installations, Ductile Iron Pipe has become often used for gravity and force main sewer applications. Following a tradition with hundreds of years of history,

A New Piston Motor for Horizontal and Directional Drilling

SPE Eastern Regional Meeting
Abstract Mud motors, also known as downhole motors, are positive displacement motors widely used in horizontal and directional drilling. Conventional mud motors rely on a rotor-stator assembly, where pressurized drilling fluid generates rotational motion to drive the drill bit. This study introduces a novel piston motor, designed to more

Overview of Horizontal Directional Drilling for Utility Construction

1999
Abstract : Horizontal directional drilling (HDD) is a versatile form of utility construction and has seen enormous growth in the last decade as it offers a clear alternative to conventional methods. Drilling is conducted in both the vertical and horizontal direction and can be steered within limits, dependent upon subsurface conditions. HDD can install
