Horizontal Directional Drilling (HDD) Good Practices Guidelines-David Bennett Horizontal Directional Drilling (HDD)-David Willoughby This is a complete sourcebook of information on Horizontal Directional Drilling, the installation of pipelines and utilities beneath obstacles such as water and roadways. Horizontal Directional Drilling, Rev/05 PART 2 - PRODUCTS MATERIALS A. General 1. Pipe for Horizontal Directional Drilling (HDD) construction shall be Ductile Iron, Class 53, flexible restrained joint pipe with a spigot retainer weldment, in accordance with Section , Ductile Iron Pipe, Fittings, and Accessories. 2. This Manual of Practice addresses the design of major pipeline or duct segments to be installed by horizontal directional drilling (HDD). HDD is a trenchless excavation method that is accomplished in three phases and uses a specialized horizontal drilling rig with ancillary tools and equipment.
Horizontal Directional Drilling Plan describing the equipment, methods, procedures (pilot hole drilling, insertion, reaming, pullback, coating manufacturer's operation manual for this machine. 4. CONTRACTOR'S construction drawings, specifications, and contingency plans shall be submitted for the following items. Horizontal Directional Drilling (HDD) is a construction technique whereby a tunnel is drilled under a waterway or other designated area, and a pipeline or other utility is pulled through the drilled underground tunnel. The underground tunnel follows an arc line from the entry point, down. Installing underground utility lines safely using horizontal directional drilling (HDD) equipment prevents the drill from hitting and breaking existing underground utility lines (i.e., electrical, water, sewage, gas, steam, chemical). If the drill contacts underground electrical wires, the operator may be electrocuted.

Casing Seat Calculation For Directional Horizontal Drilling. Once the target constraints have been defined, the wellbore must be planned. Review the offset data to determine where casing must be set (Casing Setting Depth). Decide what bit size will be required to drill the horizontal section. In many horizontal wells, the casing is set through the build curve to eliminate any potential problems with formations above the pay zone. The Horizontal Directional Drilling Process The tools and techniques used in the horizontal directional drilling (HDD) process are an outgrowth of the oil well drilling industry. The components of a horizontal drilling rig used for pipeline construction are similar to those of an oil well drilling rig with the major exception being.
