Roger Bartlett WILLIS 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).

  • Publication number: 20230349632
    Abstract: The disclosure provides a system to capture greenhouse gas, such as carbon dioxide, from exhausts of greenhouse gas emission sources on industrial sites, such as industrial grade power generators, and liquefy it for temporary onsite storage for collection and transportation to specifics sites for permanent carbon dioxide sequestration or utilization. The system can integrate the greenhouse gas emission source, with exhaust gas collection equipment, greenhouse gas capture equipment, greenhouse gas liquification equipment, and greenhouse gas fluid storage equipment for the onsite collection of the captured greenhouse gas from the greenhouse gas emission sources.

  • Publication number: 20230349267
    Abstract: The disclosure provides a system to capture on-site greenhouse gas, such as carbon dioxide, from exhausts of greenhouse gas emission sources. The carbon dioxide is mixed with water to form a carbonated fracking fluid portion to combine with a proppant fracking fluid to form the fracking fluid for injection into a subsurface. The carbon dioxide in the carbonated fracking fluid portion is then sequestered into the formation through chemical attraction. The system can be an in-situ closed loop system in that the capture of the wellsite’s carbon dioxide emissions and injection into the formation occur at the same wellsite or nearby wellsites in the same field to avoid long-term surface storage and transportations. The system can be modular, scalable, and transportable. The system can be installed as decentralized individual units coupled with each greenhouse gas generating equipment at the wellsite..

  • Publication number: 20230349266
    Abstract: The disclosure provides a modular, scalable, and transportable system for capture and sequestration of wellsite greenhouse gas emissions, such as carbon dioxide, by integrating exhaust gas collection equipment, greenhouse gas capture equipment, greenhouse gas compression equipment, and a method enabling sequestration of the gas into well construction equipment and processes. The captured gas can be compressed or otherwise formed into a denser gas fluid, and injected into a geological formation, such as a shale formation. Enhancements to fracking processes can be provided by intercalating or otherwise mixing the gas fluid with fracking fluid. The gas fluid can be geologically sequestered by its interaction with and adsorption into the formation. The sequestered gas fluid can enhance hydrocarbon recovery by reduction of oil interfacial tension in the formation and desorption of methane from the formation. The gas fluid can also be absorbed into the formation or sequestered in other wells or storage facilities.
