Generally, a   hydraulic drilling machine   spread has a smaller footprint than a conventional drilling rig. This is, in part, because hydraulic drilling usually involves smaller hole sizes requiring smaller drill string diameters, smaller OD and lighter BHAs, and smaller mud systems and pumps that require only the circulation rates necessary to clean the hole. All of this means less areal space is required on the wellsite for the equipment spread.   Less equipment, lower pump rates, and smaller horsepower requirements also mean less fuel consumption and fewer air emissions. There is less equipment on the location, so exposure risk to leaks or spills is reduced. Smaller hole sizes also mean that a smaller cuttings volume must be handled, and the risk of a cuttings spill is also reduced.   The snub drilling spread may be required to drill the same size holes as the conventional drilling rig. It does not have a substructure and mast, however, and most of the other equipment is smaller. S
