Patent application numberDescriptionPublished
20090301634METHOD AND DEVICE FOR APPLICATION OF A STRIP MATERIAL - The present invention relates to a method and a device for the application of a strip material to a substrate. Particularly, the present invention relates to a automatic application of an elongate strip of elastic material to a substrate. The present invention further relates to a device and a method for applying a seal strip such as a weatherstrip seal to a substrate. The elongate strip is advanced by drive means and positioned on a substrate by means of an application unit. The stress of the elongate strip is controlled by a stress control unit which is positioned in the area between the drive means and the application unit.12-10-2009

20080200352Degradable Material Assisted Diversion or Isolation - A method for well treatment by forming a temporary plug in a fracture, a perforation, a wellbore, or more than one of these locations, in a well penetrating a subterranean formation is provided, in which the method of well treatment includes: injecting a slurry comprising a degradable material, allowing the degradable material to form a plug in a perforation, a fracture, or a wellbore in a well penetrating a formation; performing a downhole operation; and allowing the degradable material to degrade after a selected time such that the plug disappears.08-21-2008
20080289823Degradable Material Assisted Diversion or Isolation - A method for well treatment by forming a temporary plug in a fracture, a perforation, a wellbore, or more than one of these locations, in a well penetrating a subterranean formation is provided, in which the method of well treatment includes: injecting a slurry comprising a degradable material, allowing the degradable material to form a plug in a perforation, a fracture, or a wellbore in a well penetrating a formation; performing a downhole operation; and allowing the degradable material to degrade after a selected time such that the plug disappears.11-27-2008
20100252264METHOD OF TREATING A SUBTERRANCAN FORMATION WITH COMBINED BREAKER AND FLUID LOSS ADDITIVE - A method of treating a subterranean formation penetrated by a wellbore is accomplished by introducing a fluid into the wellbore containing a combined fluid loss additive and breaker. The combined fluid loss additive and breaker is formed from particles of an organic peroxide provided on a substrate. The particles are sized to facilitate fluid loss control. A treatment operation is carried out wherein a treatment fluid viscosified with a polymer is introduced into the formation through the wellbore.10-07-2010

20080269080Wellbore Treatment Compositions Containing Foam Extenders and Methods of Use Thereof - This invention relates to fluid compositions used in treating a subterranean formation. In particular, the invention is aqueous wellbore treatment compositions which are foams containing a viscosifying agent, a foam extender, a gas component, and a surfactant, as well as methods of forming such fluids, and uses thereof. The viscosifying agent may be a hydratable polymer, viscoelastic surfactant, or heteropolysaccharide. The foam extender may be a material such as a polyoxyalkyleneamines, ethylenepolyamines, tertiary polyamines, bicarbonate, carbonate, phosphate, or sesquicarbonate.10-30-2008

20110089326Positron emission tomography and optical tissue imaging - A mobile compact imaging system that combines both of the imaging system of and optical imaging into a single system which can be located in the operating room (OR) and provides faster feedback to determine if a tumor has been fully resected and if there are adequate surgical margins. While final confirmation is obtained from the pathology lab, such a device can reduce the total time necessary for the procedure and the number of iterations required to achieve satisfactory resection of a tumor with good margins.04-21-2011
