Latest Patents
One of his latest patents is titled "Method of well completion with casing gel." This innovative method allows for much of the well casing to be recovered if the well is later abandoned. The process involves filling the lower portion of the annulus with a conventional cementitious material while the upper portion is filled with an aqueous gel. This gel comprises effective quantities of water, a water-soluble alkali metal silicate, and a water-soluble metal compound that releases multivalent metal cations. This method enables the recovery of a significant portion of the casing after severing it above the set cementitious material.
Another important patent by Root is the "Method of controlling fluid loss from thixotropic cement." This patent describes a technique for cementing a well using a thixotropic cement slurry. The method involves preceding the slurry with a fluid that contains water, a water-soluble alkali metal compound, and a water-dispersible cellulose compound. This combination effectively controls fluid loss from the slurry, enhancing the cementing process.
