Patents by Inventor Neil Kelsall

Neil Kelsall 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).

  • Patent number: 9638818
    Abstract: A technique is designed to facilitate obtaining of acoustic data. The technique comprises traversing a tool through a subterranean formation from a first depth to subsequent depths. The tool receives a seismic signal during predetermined time windows. The seismic signal is generated by a seismic source which is activated at varying times relative to the predetermined time windows based on the depth of the tool.
    Type: Grant

  • Patent number: 9494031
    Abstract: A technique facilitates efficient data transfer during a drilling operation. The drilling operation involves deploying a drill string downhole and rotating a drill bit to cut a borehole into a subterranean formation. While the drill bit is on bottom, real-time sensor data is transmitted to a surface location or other suitable location via a data transmission system. The transmission of current or real-time sensor data is stopped when the drill bit is moved off bottom. While the drill bit is off bottom, previously recorded data is sent uphole.

  • Patent number: 8439130
    Abstract: An apparatus and method are provided for obtaining formation data while drilling. The apparatus may include a drill string and a plurality of sensors. At least two of the plurality of sensors are spaced apart along the drill string a approximately the same distance as a length of a segment of the drill string. The segment of the drill string is either added to or removed from the rest of the drill string as the drill string moves in the borehole during a drilling operation. The method may include providing numerous sensors along a drill string and repeating a cycle of various functions. The cycle may include performing an operation moving the drill string relative to the borehole and stopping movement of the drill string. Additional functions may include changing an overall length of the drill string and performing the formation property while the drill string is relatively stationary.

  • Publication number: 20120147703
    Abstract: A technique is designed to facilitate obtaining of acoustic data. The technique comprises traversing a tool through a subterranean formation from a first depth to subsequent depths. The tool receives a seismic signal during pre-determined time windows. The seismic signal is generated by a seismic source which is activated at varying times relative to the predetermined time windows based on the depth of the tool.
