2016 Large Directional Drilling Rig Census

摘要

When horizontal directional drilling (HDD) professionals discuss the size of an HDD rig, they typically refer to the maximum pullback force the unit can develop. The most common industry standard for a large directional drilling unit is defined as having a minimum of 100,000 pounds of pullback force. In addition to pullback, other common specifications are rotary torque of drill stem, rotation speed and the size of drill pipe. Pipeline & Gas Journal's 2016 census of large horizontal directional drilling contractors is an effective tool in managing a successful HDD operation, by assisting in selection of the right size of rig to fit specific project needs.
