  • Publication number: 20140262285
    Abstract: A method for stimulating or fraccing an oil or a natural gas well by adding a liquefied hydrocarbon such as liquid petroleum gas and liquefied natural gas, a proppant and a diluent such as carbon dioxide, nitrogen or mixtures thereof to the well. The order of addition is typically liquefied hydrocarbon then diluent but this order can be reversed and in other circumstances the liquefied hydrocarbon and diluent can be mixed together and fed to the well as a mixture.

  • Publication number: 20140113841
    Abstract: Stable, gas-filled bubbles on the surface of proppant particles are formed by placing proppant in selected organic solvent having a much greater solubility of a selected gas compared to water, pressurizing the solvent with the selected gas, e.g., nitrogen, at pressures equal of greater than the operating pressure for a set time period to achieve saturation, and then replacing the solvent with water before reducing the pressure back to operating pressure level to create a local supersaturation near the solvent-solid interface, which will result in gas-filled bubble formation on the surface of proppant particles. The pressurized mixture of bubble surrounded proppant particles and water can then be combined with a respective fracturing fluid, e.g., slick water or carbon dioxide and/or nitrogen foam or an emulsion, which can be used in oil or gas producing wells to improve efficiency of hydraulic fracturing thereof.

  • Patent number: 7511501
    Abstract: Systems, methods and apparatus are provided through which in some embodiments a thermal sensor of a magnetic coil of a magnetic resonance imaging system (MRI) is positioned, placed and/or mounted externally to the magnetic coil. The external placement of the thermal sensor does not require replacement of the entire magnetic coil, yielding less expensive replacement of a failed thermal sensor.

  • Patent number: 5749376
    Abstract: A medical method utilizes a medical instrument such as a suturing needle made of biocompatible material. In addition, a medical operating room is provided with a container of a solvent fluidic material. During a medical procedure, the instrument is used to operate on a patient in the operating room. Upon completed use of the instrument, it is deposited in the container in the operating room, whereupon the instrument dissolves in the container.

  • Patent number: 5242398
    Abstract: A catheter assembly comprises a catheter and a sheath enclosing the catheter to preserve the sterility thereof, the sheath being provided with a plurality of fold lines which form accordion-like pleats to enable a collapse of the sheath at a point of insertion of the catheter into a patient. The sheath is provided at a distal end of the catheter with a flange for engaging a patient during an insertion of the catheter into the patient. A catheter assembly also comprises an anchor balloon attached to the catheter at a distal end thereof, an ancillary balloon attached to the catheter at a point spaced in a proximal direction from the anchor balloon, a tube connecting the ancillary balloon to the anchor balloon so as to enable communication therebetween, and a flow stop mounted to the catheter for preventing fluid from returning to the tube from the anchor balloon upon a pressurization of the anchor balloon with fluid forced from the tube by an application of pressure to the ancillary balloon.
