  • Patent number: 8997855
    Abstract: An apparatus includes a body shaped to deform a wellbore tool in a predetermined manner. A vibration device applies a vibration to the body to reduce a frictional force caused when the body deforms the wellbore tool. In one arrangement, the vibration devices imparts a resonant wave motion to a swaging apparatus that is being pushed through a passage of a wellbore tubular. A swaging body vibrates at a resonant frequency along the long axis of the wellbore tubular and/or normal to long axis of the wellbore tubular. The relative motion between the swaging body and the tubular member reduces the force required to expand the wellbore tubular. Optionally, a controller operatively connected to the vibration device adjusts the operation of the vibration device in response to the sensor measurements of the vibrations in the swage body.

    Abstract: A system is provided for communicating within a borehole using controlled vibrations. A movement mechanism uses mechanical energy provided by a mechanical energy source to enable translational movement of a first surface relative to a second surface to allow the first surface to repeatedly impact the second surface to produce a plurality of vibration beats. The vibration beats will occur whenever the mechanical energy is provided by the mechanical energy source at one of at least three impact levels. A vibration control mechanism selectively controls an amplitude of the plurality of vibration beats to encode information therein.

  • Patent number: 8939200
    Abstract: Selected designs for reciprocating pumps and down-hole well-stimulation equipment reflect disparate applications of identical technical principles (relating to, e.g., the vibration spectrum of an impulse). In certain of these designs, the vibration spectrum is controlled, suppressed and/or damped using tunable components to limit destructive excitation of resonances; in others the vibration spectrum is tuned at its source for maximum resonance excitation. For example, tunable fluid ends control valve-generated vibration to increase fluid-end reliability. By down-shifting the frequency domain of each valve-closing impulse shock, initial excitation of fluid end resonances is minimized. Subsequent damping and/or selective attenuation of vibration likely to excite one or more predetermined (and frequently localized) fluid end resonances represents further optimal use of fluid end vibration-control resources.

  • Publication number: 20140216727
    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.

  • Patent number: 8069914
    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: 8047282
    Abstract: The present disclosure is directed to a system and method for sonically activating cement slurries. In some implementations, a method of treating a subterranean formation includes positioning a settable composition including a capsule in a wellbore. The capsule is used to increase a setting rate in response to at least sonic signals. A sonic signal is transmitted to at least a portion of the settable composition to release an activator from the capsule.

  • Publication number: 20110198093
    Abstract: A downhole tool having a body, a transducer within the body, and an opening formed through a sidewall of the body. The opening provides a port through which the transducer can communicate from within the body. An elastomeric boot in the body covers the opening and is a barrier that prevents fluid ingress into the downhole tool. An expandable sleeve envelopes the elastomeric boot and provides support that limits bulging of the elastomeric boot from within the body through adjacent openings in the body. An example sleeve is made from elongated members woven into a tubular.

  • Publication number: 20110174490
    Abstract: A system and method for performing a fracture operation on a well site having a subterranean formation with a reservoir therein is provided. The method involves measuring at least one seismic wave before and after stimulating the subterranean formation, comparing the seismic waves measured before the stimulation of the subterranean formation to the seismic waves measured after stimulation of the subterranean formation, and determining at least one fracture parameter of the subterranean formation from the compared seismic waves.

  • Patent number: 7980301
    Abstract: The method and apparatus for dampening of sudden shocks in the wells filled by liquid wherein the tubing pump is used in which on upstroke of pumping unit the damper plunger and tubing pump plunger are moving in concordance thereby compressing the liquid contained within the damper chamber and allowing the liquid inside the damper chamber to be discharged into the internal volume of tubing string above damper plunger providing a dampening counterforce inside the damper chamber, i.e. when the damper plunger is displaced upwardly in the elongated damper cylinder, the damper plunger having a diameter smaller than diameter of the tubing pump plunger causes the compression of liquid inside the damper chamber thereby creating a dampening force.

  • Publication number: 20110139440
    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: 20110139441
    Abstract: The invention provides a system, method and downhole tool for stimulating a borehole of wells in reservoir. The invention allows a user to determine the type of stimulation adequate to promote production in a reservoir, and apply one or more treatments to each individual well by activating one or more modules comprised in the downhole tools. Furthermore, the tool comprises sensors that collect information in real-time of the state of the reservoir. The data collected is processed and newly acquired data is compared with previously acquired data to assess the development of production and further plan treatment strategies to optimize production.
