Latest Patents

Among his latest patents are two groundbreaking inventions. The first, titled "Sustainable Two-Component Annular Grout Composition and Method for Use with a Tunnel-Boring Machine," introduces a novel method for backfilling gaps created by tunnel boring machines. This composition utilizes a two-component system: a non-cement slurry made from fluidized bed combustion ash, such as coal ash, and an alkali silicate like sodium silicate. The innovation allows effective integration with ordinary Portland cement and metakaolin, creating a sustainable and efficient grouting solution.

The second patent, "Method for Plugging and Abandoning Oil and Gas Wells," outlines a method and agent designed to promote accelerated creep deformation in shale rock formations. By introducing a fluid containing alkali silicate into the annular space between the shale and casing string, this technique facilitates the closing of abandoned wells. It has been notably found that lithium silicate yields the strongest bond between shale and casing, making it a preferred material for well abandonment processes.
