Latest Patents

Among his latest patents is the "Indexing Control System," which features a downhole tool assembly designed for repeated and selective hydraulic activation and deactivation. This system utilizes a spring member to bias the indexing control section towards a first axial position, while drilling fluid pressure in the tool body urges it towards other axial positions. This allows for surface-controlled activation and deactivation of downhole tools by cycling the drilling fluid pressure. Another significant patent is the "Reamer," which is a downhole apparatus that incorporates two sets of cutting structures into two integral blade stabilizers. These stabilizers are oriented both downhole and uphole, providing 360° support around the circumference of the reamer. The cutting structures consist of polycrystalline diamond cutters that are securely integrated into the reamer's body, enhancing its performance in borehole reaming.
