Latest Patents

One of his latest patents is titled "Fracturing with a mixture of carbon dioxide and alcohol." This invention outlines a method for fracturing an underground formation penetrated by a wellbore. The process involves injecting a mixture of carbon dioxide and a polar alcohol or polar glycol additive at a temperature and pressure above the critical levels of carbon dioxide. The additive, which should have fewer than 9 carbon atoms, comprises about 0.1% to 10% by weight of the injected mixture. This method is designed to create fractures in the underground formation effectively.

Another notable patent is "Recovering hydrocarbons with a mixture of carbon dioxide and alcohol." This invention describes a method for recovering hydrocarbons from underground formations by injecting a mixture of carbon dioxide and a polar alcohol or polar glycol additive. Similar to the previous patent, the additive must have less than 9 carbon atoms and is injected at critical temperature and pressure levels. The mixture is then driven through the formation, allowing for the recovery of hydrocarbons and other fluids at production wells.
