Title: Age Kyllingstad: Pioneering Innovations in Drill String Technology
Introduction
Age Kyllingstad, based in Algard, Norway, is a distinguished inventor with a portfolio of 13 patents to his name. His contributions to the field of drilling technology have provided essential advancements that improve the efficiency and effectiveness of drill strings utilized in various applications, particularly in the oil and gas industry.
Latest Patents
Among his most recent patents is a method and apparatus for reducing stick-slip oscillations in drill strings. One notable invention details a method for estimating the instantaneous rotational speed of a bottom hole assembly at the lower end of a drill string. This method encompasses driving the drill string via a drilling mechanism situated at its upper end, estimating the fundamental frequency of observed stick-slip oscillations, and determining variations in the drive torque of the drilling mechanism. Kyllingstad's invention creatively combines the known torsional compliance of the drill string with these variations to generate an output signal indicative of the instantaneous rotational speed.
Another significant patent focuses on damping stick-slip oscillations. This method involves utilizing a PI controller to manage the speed of rotation of the drilling mechanism, ensuring it absorbs most of the torsional energy from the drill string at a frequency that coincides with that of the stick-slip oscillations.
