Pipeline Design for Installation by Horizontal Directional Drilling.
Pipeline design for installation by horizontal directional drilling Directional drilling (sometimes known as slant drilling outside the oil industry) is the science of drilling non-vertical wells. Directional drilling can be broken down into three main groups: Oilfield Directional Drilling, Utility Installation Directional Drilling (commonly .

Horizontal directional drilling poses its own special problems, not the least of which are those caused by trenchless excavation, a three-phase method, and specialized tools, rigs and equipment. This manual of practice includes such topics as predesign surveys, including subsurface sub·sur·face
