| PURPOSE: A drilling structure using the velocity of flowing water is provided to drill a rock even in a mountain which does not have electricity. CONSTITUTION: A drilling structure using the velocity of flowing water is composed of a drill(5), a pillar, rotary wings(4), bearing housings(3), horizontal shafts(8), and fixtures. The drill drills a rock using the velocity of flowing water. The pillar is coupled to the drill. The rotary wings are coupled to the pillar and are rotated by the flowing water. The bearing housings support the pillar. The horizontal shafts are connected to the bearing housings. The fixtures connect the horizontal shafts to the ground. | ||||||

| 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. | ||||||

| 47 | Device for high-speed boring of stepped post-holes | US44415 | 1979-06-01 | US4263975A | 1981-04-28 | Jacques Dagnaud |
| The bottom annular flange of a bearing sleeve which is displaceable with respect to a support frame is applied against the ground surface around the zone of a hole to be bored. A cylindrical cutter placed around a boring mandrel attached to the operating rod of a jack is downwardly displaced only at the end of travel of the jack, driven into the ground with the boring mandrel and forms a cylindrical recess around the upper end of the bore-hole. The portion of soil which is trapped between the cylindrical cutter and the boring mandrel is removed automatically after simultaneous withdrawal of mandrel and cutter. A post can be driven into the bore-hole, cement or concrete being then poured into the cylindrical recess. | ||||||

| A logging tool electronics system is disclosed (FIG. 1) with noise minimization features and pulse compression signal processing techniques to improve the signal-to-noise ratio of array induction logging tools. The borehole is radiated with a magnetic field produced by a configurable multi-frequency sine wave signal stimulus section driving a fully differential single transmitter coil. Received signals from multiple mutually balanced fully differential receiver arrays are processed by receiver signal chains using adaptive algorithms under firmware control. The received signals are used to determine the conductivity and resistivity of the formation surroundin the borehole. | ||||||
