Vertikalbohrkonzept für die KTB-Hauptbohrung

The KTB Vertical Drilling Concepts is the result of the careful analysis of international experiences and two major research and development projects. The verticality of the borehole influences directly the torque and drag values on drill string and the forces acting on the casing during the running procedure. The KTB Vertical Drilling Concept is presented and the different components of the modular assembled bottom hole assembly are described
