Micro-seismic events are generated by particles introduced into the fractures which are capable of explosive or chemical reaction. In one method, treated proppant having a reactive coating is positioned in the formation during fracturing and reactive particles are introduced. In another method, reactive particles having a reactive core and a non-reactive coating are positioned in the fractures and react upon removal of the non-reactive coating, such as by dissolving, and reaction with a reactive particle. The waves generated by the micro-seismic events are used to map fracture space.

    Abstract: Acoustic radiators for coal bed methane or shale gas production are configured to be strategically placed on drillstrings within gas production exhaust boreholes and hydraulically powered so they will radiate intense harmonic sonic waves to shake the solid media immediate to the wall areas. The gas volume output that can be realized by an exhaust well depends highly on the permeability of the media, especially at inside faces of the borehole. The shaking half-opens up fractures and pores in the solid media. Thus the permeability of the media to gas improves under such shaking and gas collection efficiencies are improved. The beneficial effects can be increased by locating two or more acoustic radiators proximate to one another in a phased relationship.

The metallic plasma emits a pressure pulse and shockwaves, which are directed into the fluid medium. Nonlinear, wide-band, periodic and elastic oscillations are generated in the fluid medium, including resonant oscillations by passage of the shockwaves.

  • Publication number: 20140014328
    Abstract: The invention is directed to a hydraulic actuated pump system which lifts production fluids and re-circulating hydraulic fluid from a petroleum well. Additives may be added to the hydraulic fluid to apply direct chemical treatment to the production formation. A sonic stimulator may be included to stimulate and produce the same liquids from the horizontal section of the well.

  • Patent number: 8613312
    Abstract: The invention provides an apparatus and method for stimulating a borehole of a well. The invention provides an apparatus that generates low-frequency seismic type elastic waves that propagate to the geologic formation and in order to enhance the movement of fluids in the geologic formation toward a well. The apparatus may operate automatically driven by a power source that may be located on the ground surface. The regime of operation may be determined by user input. Operation of the apparatus may carried out while production of a natural resource is ongoing.

  • Publication number: 20130333896
    Abstract: A method for disrupting an obstruction from a wellbore includes determining a location of an obstruction within a wellbore. An ultrasound transducer is deployed down an interior of a casing in the wellbore. Ultrasound energy is focused, using the ultrasound transducer, to the determined location of the obstruction and the obstruction is disrupted using the focused ultrasound energy.

  • Publication number: 20130220598
    Abstract: An ultrasonic fracking system and methods of using the same to extract hydrocarbons from underground geological formations (e.g., oil shale, coal beds, etc.) are disclosed. The system includes piezoelectric devices that are used to produce ultrasonic mechanical vibrations and induce fractures in the geological formations. In one embodiment, a system for extracting underground hydrocarbons comprises a plurality of piezoelectric devices capable of producing mechanical waves sufficient to fracture oil shale and other geological formations, a system of delivery for innocuous proppants to create a path of least resistance for enhanced hydrocarbon flow, and a vacuum pump connected to the fractures created by the piezoelectric devices to assist in removing the hydrocarbons.
