The central axis line of a well or a pipeline with a position vector at each point of trajectory given as:
{\bf r} = {\bf r}(l)= \{ x(l), \, y(l), \, z(l) \} |
where
position vector of trajectory point with being a ture vertical direction | |
path length from pipeline intake point | |
well or pipeline intake point coordinates (usually ) |
