Latest Patents

Stephen H Lewis holds a patent for a "Shoe track saver and method of use." This invention involves an inline component for a liner assembly, specifically designed for use in deviated wellbores. The component features a series of offset passages that create sufficient turbulence in the circulating cement during a cementing job. This innovation effectively eliminates the phenomenon of roping, which occurs due to inefficient displacement of mud with the circulating cement. The multi-component inline device is equipped with peripheral seals to prevent leak paths along the inside wall of the casing being cemented. The offset flow passages are presented in individualized components that are rotationally locked to each other and include peripheral sealing devices. The stack of components is retained within the casing to prevent longitudinal movement during the pumping of cement. The preferred materials for this invention are soft metallics, which facilitate drilling out if required. The interlocking nature of the components also eliminates relative rotation, making the drill-out process more efficient.
