Publication number: 20210389391Abstract: A vertical bipole source in a borehole generates a vertical bipole flow. The vertical bipole flow generates mutually orthogonal time-domain B-field data. Magnetic receivers at a surface location receive the time-domain B-field data and determine elements of a hydrocarbon reservoir using a 3D EM inversion technique. The vertical bipole source may extend into the borehole or be a virtual bipole source located at a surface location above a reservoir.Type: ApplicationFiled: February 23, 2021Publication date: December 16, 2021Inventors: Michael S. Zhdanov, Leif H. Cox, Alex Gribenko, Hideaki Ban, Hiroshi Chiba

Patent number: 10926134Abstract: A method for locating a golf ball including changing a temperature of a golf ball from a first temperature to a second temperature before use or marking the ball by reflective (mirror) or fluorescent material (e.g., NIR-IR fluorescent dye). The temperature changed ball is struck. Using either a thermal imaging camera with an imaging processing unit or a near-infrared (NIR) imaging camera with an imaging processing unit to produce a digital image of a part of the golf course with a potential golf ball location. An image processing technique is applied to produce an enhanced image of the golf ball location. A thermal imaging camera and a NIR imaging camera for locating a golf ball are described. A non-transitory computer readable media is described.Type: GrantFiled: December 17, 2018Date of Patent: February 23, 2021Assignee: TechnoImaging, LLCInventors: Michael S. Zhdanov, Leif H. Cox, Vladimir Burtman

Patent number: 9542359Abstract: Volume imaging of geological structures and/or man-made objects having physical property using geophysical field sources and/or sensors mounted from at least one data acquisition system. The sources may include natural field sources and/or man-made sources. The sensors may measure at least one component of the geophysical field. The subsets of the geophysical survey formed by the at least one source of geophysical data are selected, and the integrated sensitivity subdomains for selected subsets of the survey are determined by determining the volumes where the integrated sensitivity of the subset is greater than a predetermined threshold. The total sensitivity is determined as the superposition of the sensitivities from all of the integrated sensitivity subdomains.Type: GrantFiled: December 28, 2012Date of Patent: January 10, 2017Assignee: TechnoImaging, LLCInventors: Michael S. Zhdanov, Leif H. Cox

Patent number: 9322910Abstract: A method for the real time volume imaging of geological structures and/or man-made objects having electrical conductivity is described, using electromagnetic (EM) sources and/or EM sensors mounted from at least one moving platform. The EM sources may include natural EM sources and/or man-made inductive sources and/or man-made galvanic sources. The EM sensors may measure at least one component of the EM field at the at least one sensor position. The EM fields measured for each combination of EM source and EM sensor may be volume imaged in real time using a moving sensitivity domain that captures the finite spatial sensitivity of each combination of EM sources and EM sensors. At least one desired property, such as conductivity, dielectric permittivity and/or induced polarization parameters, may be derived from the volume image, providing a reconstruction or classification of the physical properties of the geological structures and/or man-made objects.Type: GrantFiled: June 4, 2012Date of Patent: April 26, 2016Assignee: TechnoImaging, LLCInventors: Michael S.

Patent number: 9020205Abstract: A method of multinary inversion for imaging objects with discrete physical properties of the examined medium is described. The model parameters of the target area are parameterized in terms of a multinary function of the physical properties that accepts a finite number of discrete values from the continuum of at least one physical property. The multinary function is chosen such that the derivative of the multinary function with respect to the physical property is a continuous and known function. The imaging is based on solving the optimization problem for parametric functional of the multinary functions describing the target model parameters. The method can be applied for multi-modal imaging, such that at least one physical property representing the physical properties of the examined medium, may be derived to provide a reconstruction or classification of the physical properties of the examined medium.Type: GrantFiled: August 23, 2013Date of Patent: April 28, 2015Assignee: TechnoImaging, LLCInventors: Michael S.
