Paul Joseph Ganssle 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).

  • Nuclear magnetic resonance sensors embedded in cement
    Patent number: 11143014
    Abstract: Various embodiments include nuclear magnetic resonance (MR) sensor array systems and methods are disclosed. One such system includes a downhole casing having at least one MR sensor array peripherally coupled to an outside of the casing. At least one MR sensor array can include an MR sensor configured to monitor a cement/fluid mix composition while the cement is setting.
    Type: Grant

  • Selective NMR pulse for downhole measurements
    Patent number: 10473600
    Abstract: Various embodiments include a method for generating a pulse for use in nuclear magnetic resonance (NMR) logging. One such method generates the pulse by adjusting one or more of pulse parameters including a pulse shape, a pulse amplitude, a pulse phase, and/or a pulse frequency. The generated pulse produces a substantially uniform nuclear spin saturation or nuclear spin inversion response from a fluid. A wait time between the pulse transmission and an echo that indicates spin equilibrium has been achieved is substantially equal to a T1 time indicating characteristics of the fluid.

  • Magnetic resonance systems and methods employing multi-shape pulse sequences for parallel measurements
    Patent number: 10422914
    Abstract: A magnetic resonance method includes providing a pulse sequence that affects different measurement regions in presence of a magnetic field gradient, the pulse sequence having multiple pulse shapes and multiple characteristic interecho intervals (TEs).
