Latest Patents

One of his latest patents is the Bottom Hole Apparatus RPM Regulator. This system for drilling a wellbore includes a drill string, bottom hole apparatus, and a rotation regulator. The rotation regulator features a compound planetary gear set with both a first and second planetary unit. The first planetary unit is located in the proximal region of the rotation regulator, while the second planetary unit is situated in the distal region. The gear set incorporates a hollow central shaft that is common between the two planetary units, which have different outer diameters. A bearing is positioned between the two units, allowing the drill string, rotation regulator, and bottom hole apparatus to be connected in series. This design enables the rotation regulator to mechanically transmit the rotation of the drill string into the bottom hole apparatus.

Another notable patent is the Displacement Opening Cone for Cementing Operations. This opening cone is utilized during cementing operations in a wellbore and is part of a mechanical stage collar that includes ports activated by the cone. The opening cone features a cylindrical midsection and a conical end section, creating a hollow path. A ball is suspended in a cage within the cylindrical midsection, positioned between two profiles with sets of ribs. The second profile is designed to rupture at a predetermined pressure, releasing the ball into the conical end section to plug the hollow path and stop the flow.
