... drilling conference drill string Introduction Contrarily to rotary drilling, sliding mode is very sensitive to the friction state along the drill string. With high friction configurations, such as drilling the lateral section of an unconventional well trajectory, the drag forces become an obstacle...

Paper Number: SPE-208677-MS
... Abstract Downhole separation of rotary shouldered connections in drill strings cause immense financial loss to oil and gas operators. Unfortunately, there seems to be an increasing trend in these downhole failures, particularly in deep water operations where the surface torque is limited...

... in the industry. In there, drill strings are modelled as just torsional spring – inertia resonator(s). Z aims to cancel out torsional oscillations (and thus stick-slip) by eliminating one of the two waveguide boundary conditions. The technology eliminates damaging torsional vibrations (stick-slip), by making sure...
