A hydraulic fracturing pump system includes an electric powered hydraulic fracturing pump positioned on a support structure. The system also includes a suction stabilizer/dampener coupled to a suction end of the pump. The system further includes a compressed gas supply, fluidly coupled to the suction stabilizer/dampener, and positioned on the support structure. The system also includes a flow path between the suction stabilizer/dampener and the compressed gas supply, the flow path including at least one valve and at least one regulator configured to control flow from the compressed gas supply to the suction stabilizer/dampener.

This patent application discloses method and apparatus to cut an extended slot connecting a well to a substantial cross section of a desired producing formation whereby material can flow freely between the formation and the wellbore and at least partially overcome the flow limitations of low permeability formations without the environmental issues associated with hydraulic fracturing. It is further disclosed that the connection between said slot and the formation may be further enhanced by explosive or combustive processes that rapidly generate gas pressure within the large surface area of the slot, thereby changing its characteristics and forcing open additional fractures into the cross section of formation exposed to the slot. The method may significantly increase the recoverable percentage or natural gas from low permeability deposits such as shale and coal.

A human-powered borehole drill bridges the gap between large drilling rigs and the other less-effective manual methods. Intended mainly for developing countries, the design is affordable and also extremely simple, as very little product support or spare parts will be needed. The drill uses conventional drill pipe and drill bits allowing the drill system to mimic more conventional methods of drilling and existing hardware to maintain uniformity in drilling and easier access to more drilling products.

A reaming system including an elongated tubular housing having a first end and a fluid inlet aperture. The elongated tubular housing includes a second end having a fluid outlet aperture. The reaming system includes a first bearing pack disposed circumferentially about the first end of the housing. The first bearing pack is only of sacrificial materials which may be drilled through. The reaming system includes an auger. The reaming system includes a reaming tool functionally coupled to the auger. The reaming tool may be a tool selected from the group consisting of: a float shoe, a reamer shoe, and a guide shoe. The reaming system includes a second bearing pack functionally coupled to a bottom end of the auger. The reaming system includes a connection sub functionally coupled to a bottom end of the auger that transfers rotational motion from the auger to an attached tool.

A tool for boring holes in soil includes an elongated tubular housing which has disposed through its length a bore having an upper opening coupleable to a vacuum source and a lower opening coupled to the bore of a ring-shaped bore head having circumferentially spaced apart cutting teeth protruding downwards from the bore head. A zig-zag shaped unclogger bar disposed coaxially through the bore head and rotated by a drive shaft disposed coaxially through the tubular and housing and protruding through a bearing in an upper end of the housing and driven by a rotary power source such as an electric motor fixed to the housing fragments lumps of clay or wet soil lodged in the bore of the housing, facilitating removal of soil and clay, which are severed by twisting the tool around its longitudinal axis by manipulating handle bars protruding from the upper end of the housing.

A water drilling system includes a handheld wand having a handle portion and a distal tip. A hose connects the handheld wand to a pressurized water source. The handheld wand is controllable to selectively discharge pressurized water from a nozzle at the distal tip. A non-metallic hollow shaft of the handheld wand is configured to be thrust into ground soil. The hollow shaft extends between the handle portion and the distal tip, and the hollow shaft has an outside diameter less than an outside diameter of the distal tip.

Systems and methods for creating a weep hole in an uncured, concrete, hollow core structural component having one or more external surfaces and one or more internal surfaces. The weep hole is drilled using a drilling apparatus comprising a drill, a rotating drill bit with an internal fluid passageway, a power source, and a pressurized fluid source. Loose, uncured concrete material deposited near the weep hole on the one or more internal surface as a result of drilling the weep hole is removed by releasing pressurized fluid which flows from the pressurized fluid source, through the drill and the rotating drill bit.

A hole is formed in a drill target with improved workability. An electric work machine includes a motor, a motor housing accommodating the motor, a handle housing including a grip including a trigger switch operable to activate the motor, a reducer, a gear housing accommodating the reducer, a rotation output unit protruding frontward from the gear housing and rotatable under a rotational force transmitted from the motor through the reducer with a drill bit being attached to the rotation output unit, and a handle fastened to the gear housing and at least partially located laterally from the gear housing.

A vertical tiller comprises a rider disc or foot at the bottom of a helix or screw/auger, with the assemble further comprising angled winged appendages having angled sweep sections. The assembly further comprises a turned leading appendage. The turned leading appendage keeps the assembly relatively vertical to prevent the other appendages from fouling, cutting or entangling with cloth, wire or other elements often found at the bottom of planting pots, wire baskets and planting beds. The vertical tiller performs maceration and aeration within soil and provides a level of safety by the angled appendages that bounce off of a user's foot. The invention is well suited for remixing and amending soil and is intended for light soils having minimal rocks and large roots. The disclosed wing design assists having greater control over the tiller which is useful in selective tilling to promote soil biota.

Disclosed herein is a hand-held power tool including a motor housing, a motor in the motor housing, an auger coupled to the motor and having a rotational axis, and a first handle coupled to the motor housing and including a grip. In some embodiments, the rotational axis of the auger and an axis of the grip subtend to an acute angle.
