Patents by Inventor James H. Trato

James H. Trato 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).

  • Cementitious compositions and cementitious slurries for permanently plugging abandoned wells and processes and methods therefor
    Publication number: 20040256102
    Abstract: A dry cementitious composition which when slurried with water produces an economical hydraulic cementitious slurry for closing abandoned wells. The dry cementitious composition is a cement/CKD blend as the major component with a weight ratio of parts cement to parts of CKD between about 2/3 and about 3/1. Hydraulic cementitious slurries when cured can produce hard cementitious bodies which will meet or exceed the API specification for a competent hard plug. A process for blending the cement and CKD during transit from the cement source to the off-load site without requiring further blending after off-loading. Methods are provided for determining the formulation having the cheapest cost per unit volume of hydraulic cementitious slurry thereby enabling competitive quotes based on cf of hydraulic cementitious slurry required.
