Patents by Inventor John J. Ullo

John J. Ullo 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).

  • Devices for cooling and power
    Patent number: 10573574
    Abstract: Certain embodiments disclosed herein are directed to devices for cooling. In certain examples, a thermoelectric device comprising a substrate and a superlattice coupled to the substrate is disclosed. In some examples, the superlattice includes a first semi-conducting material and a second semi-conducting material coupled to the first semi-conducting material to provide an interface between the first and second semi-conducting materials.
    Type: Grant
    Filed: January 30, 2014
    Date of Patent: February 25, 2020
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: John J. Ullo, Tsutomu Yamate, Jiro Takeda

  • Method and apparatus for distinguishing hydrocarbon from fresh water in situ
    Patent number: 4577102
    Abstract: Method and apparatus for distinguishing oil from fresh water in situ in a subsurface geological formation are proposed which utilize the anomalous response of a neutron porosity tool to some oils. Apparent porosity derived from a neutron porosity investigation tool which measures spatial neutron flux distribution is compared to the porosity derived from a second investigating tool whose response is not or at least is less sensitive to the hydrogen density of the formation fluid than is the neutron porosity tool. Where a real difference is evident, oil rather than fresh water is indicated.

  • Method and apparatus for determining in situ hydrocarbon characteristics including hydrogen density
    Patent number: 4416151
    Abstract: Method and apparatus for determining the hydrogen and carbon densities of oil in situ in a subsurface geological formation are proposed which utilize the response of a neutron porosity tool to some oils. Apparent porosity derived from a neutron porosity investigation tool, which measures spatial neutron flux distribution, is compared to the porosity derived from a second investigating tool whose response is not or at least is less sensitive, say, to the hydrogen density of the formation fluid than is the neutron porosity tool. The magnitude of the difference is indicative of the hydrogen and carbon densities of the oil.
