Latest Patents

One of his latest patents is a "Method and system for radially expanding a tubular element." This invention relates to a system and method for radially expanding a tubular element. The method involves bending the tubular element radially outward and in an axially reverse direction to form an expanded tubular section around an unexpanded tubular section. The bending occurs in a designated bending zone, and the length of the expanded section is increased by moving the bending zone in the axial direction relative to the unexpanded section. The method also includes heating the bending zone, with several embodiments described to enable this heating.

Another significant patent is the "Method of determining drill string stiffness." This method provides a way to determine the rotational stiffness of a drill string used for drilling boreholes in earth formations. It involves determining the time derivative of the drill string torque during drilling at a specific time when stick-slip occurs, as well as the nominal rotational speed of the drill string. The rotational stiffness is then calculated based on a selected relationship between the time derivative of the torque and the nominal rotational speed.
