    摘要： Various embodiments of reduced-size vehicles such as all-terrain vehicles (ATVs) and utility vehicles (UVs) are disclosed herein. In at least some embodiments, the vehicles include frames that are wider near the front and rear sections of the vehicles than within the mid-sections of the vehicles. This, in combination with the use of shock-absorbers that are substantially vertically oriented, allows for the opening-up of large interior cavities within the front and rear sections of the vehicles within which can be positioned large front and rear internal compartments that can provide storage/carrying capacity as well as added buoyancy for the vehicle, among other things. Also, in at least some embodiments, the vehicles can include special cooling and/or exhaust systems having components that are positioned substantially within the mid-sections of the vehicles, thus further increasing the amounts of space available for the cavities/compartments within the front and rear sections of the vehicles.

    摘要： A water-base fluid for use in drilling wells and other drilling operation includes a shale clay which swells in the presence of water. The fluid preferably includes: an aqueous based continuous phase, and a shale hydration inhibition agent having the formula: H—(OR)x—[—NH—CH2—CH2—CH2—O—CH2—CH2—NH—]—(R′O)y—H wherein R and R′ are independently selectable alkylene groups having 2 to 4 carbon atoms, and wherein x and y have independently selected values such that the sum of x and y is at least 1. The shale hydration inhibition agent should be present in sufficient concentration to reduce the swelling of the shale clay. The fluid may be used for formulating drilling fluids such as water-base drilling muds or clear brine drilling fluids. The fluid may also be used in the slurrification and disposal of drill cuttings that contain water swellable clays or shale clays.

    摘要： Methods, systems, and articles of manufacture consistent with the present invention provide for determining the orientation of natural fractures in the Earth resulting from hydraulic fracturing treatment. Data attribute information from a far-field point-source signal profile for a microseismic event is extracted in the time domain. An estimate of the orientation of the natural fracture is calculated in the time domain based on the extracted data attribute information.

    摘要： A water-base drilling fluid for use in drilling wells through a formation containing a shale which swells in the presence of water. The drilling fluid preferably includes: an aqueous based continuous phase, a weight material, and a shale hydration inhibition agent having the formula: H2N—R—{OR′}x—Y in which R and R′ are alkylene groups having 1 to 6 carbon atoms and x is a value from about 1 to about 25. The Y group should be an amine or alkoxy group, preferably a primary amine or a methoxy group. The shale hydration inhibition agent should be present in sufficient concentration to reduce the swelling of the shale. Also inclusive of the present invention is a method of reducing the swelling of shale clay encountered during the drilling of a subterranean well, the method comprising circulating in the well a water-base drilling fluid formulated in accordance with the present invention.

    摘要： A tunnel thruster system for a vessel. The tunnel thruster system includes a thruster propulsion mechanism including a drive unit driving a transmission and propeller assembly located within a thruster tunnel. The thruster tunnel comprising a propeller section, first and second tapered tunnel sections interconnected with one another by the propeller section, the propeller section and the first and the second tapered tunnel sections oriented substantially transversely to a keel of the vessel and accommodating the transmission and propeller assembly. Each tapered tunnel section extends from the propeller section to a tunnel opening through a hull of the vessel. Diameters of the first and the second tapered tunnel sections corresponding to a diameter of the propeller section at the propeller section and taper outward toward a larger diameter at each of the corresponding tunnel openings through the hull of the vessel.
