Gordon G. Sorrells 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: 6985816
    Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide for determining the orientation of natural fractures in the Earth resulting from hydraulic fracturing treatment. Data attribute information from a far-field point-source signal profile for a microseismic event is extracted in the time domain. An estimate of the orientation of the natural fracture is calculated in the time domain based on the extracted data attribute information.

  • Patent number: 5377104
    Abstract: Using geologic hydraulic fracturing methods and subterranean waste injection and disposal processes well known in the petroleum production industry, hazardous wastes are pulverized, mixed to create a slurry, and injected into a subsurface hydraulic fracture rock formation via a perforated deep well. Injection of the slurry at pressures exceeding the rock's minimum principle stress generates microseismic signals whose sources correspond to the locations and geometry of an expanding hydraulic fracture zone. These signals are detected with seismic sensors. Advanced, Real Time, Passive Seismic Imaging (PSI) methods are applied for automatic data acquisition, compression, analysis and calculation to locate the sources of the signals and to map the dimensions and geometry of the fracture zone in real time. Computer visualization codes are employed to present injection data and the fracture zone location, dimensions and geometry for human interpretation and decisions.
