Patents by Inventor Arjun Vijayakumar

Arjun Vijayakumar 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).

  • Laser spectroscopy for downhole sensing of gases and fluids
    Patent number: 9453938
    Abstract: A method for spectroscopic analysis of a fluid using electromagnetic radiation from lasers is provided. In one embodiment, the method includes sampling formation fluid within a well and determining formation fluid properties for the sampled formation fluid through downhole fluid analysis. Determining formation fluid properties for the sampled formation fluid can include using a spectrometer having a plurality of quantum cascade lasers to determine optical properties of the formation fluid and determining levels of multiple chemical species in the formation fluid using the determined optical properties of the formation fluid. Various other methods, systems and devices are also disclosed.
    Type: Grant
