Patents by Inventor Nikolay N. Velker

Nikolay N. Velker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Single detector detection and characterization of thermal and epithermal neutrons from an earth formation
    Patent number: 9329303
    Abstract: An apparatus for detecting thermal and epithermal neutrons. The apparatus includes a first radiation responsive element configured to absorb substantially all incident thermal neutrons and produce first light scintillations indicative of the absorbed thermal neutrons and a second radiation responsive element configured to produce second light scintillations indicative of at least epithermal neutrons that traverse the first radiation responsive element. Also disclosed are borehole logging methods and apparatuses for estimating formation properties using nuclear radiation, particularly an apparatus and method for estimating parameters of a formation. The method may include using neutron count rate information from a detector to model porosity or salinity. The apparatus includes a processor and storage subsystem with a program that, when executed, implements the method.

  • Apparatuses and methods for detection of radiation including neutrons and gamma rays
    Patent number: 8969813
    Abstract: A scintillation detector includes: a photodetector; a scintillating material configured to emit light in response to exposure to ionization particles; an optically transparent material having a light absorption coefficient that is less than a light absorption coefficient of the scintillating material, the optically transparent material optically coupled to a surface of the scintillating material and configured to transmit the emitted light; and a reflective material at least partially surrounding the scintillating material and the optically transparent material, the reflective material configured to reflect the emitted light and direct the emitted light toward the photodetector.
