... Abstract An explicit solution to the general 3D point to target problem based on the minimum curvature method has been sought for more than four decades. The general case involves the trajectory's start and target points connected by two circular arcs joined by a straight line with the position...

... by the authors. The electrical plasma-based tool changes completely from its inception the paradigm of the drilling as well as casing milling. The most important advance in comparison to conventional plasmatorch technology is that the electrical arc with temperatures of tens of thousands of degrees Kelvin heats...

...Extending the Well Path Well-path trajectories are typically designed using well-defined arcs of constant curvature for the transition well paths between the tangent sections. Transition curves are defined as the curve segments connecting the well-path tangent sections to the build or drop...
