Phillip Wills 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).

  • Dual piston, single phase sampling mechanism and procedure
    Patent number: 7621325
    Abstract: A method and apparatus for maintaining the single phase integrity of a deep well formation sample that is removed to the surface comprises a vacuum jacket insulated single working cylinder divided by two free pistons into three variable volume chambers. The intermediate chamber is pre-charged with a fixed quantity of high pressure gas. Wellbore fluid freely admitted to one end chamber bears against one free piston to further compress the gas. The formation sample is pumped into the other end chamber to first, displace the wellbore fluid from the first end chamber and, sequentially, to further compress the gas to preserve the sample phase state upon removal to the surface.
    Type: Grant
    Filed: January 29, 2007
    Date of Patent: November 24, 2009
    Assignee: Baker Hughes Incorporated
    Inventors: Houman M. Shammai, John M. Michaels, James T. Cernosek, Michael J. Moody, Phillip Wills
