Pipeline Design for Installation by Horizontal Directional Drilling.0784408041Pipeline 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 . Am.
