n: In this method,the wellbore axis between two adjacent test points is considered to a space curve and the horizontal projection of this curve is considered to a section of arc with unchanged curvature

n: the configuration of pipe when it enters the water from a stinger of a lay barge in pipeline construction. The overbend is closest to the barge, and the sag bend is on the seafloor. Compare J cunle. See sag bend.

n: a change in the configuration of a pipeline whereby the pipe is curved from the horizontal to a 9()!1 vertical run, then curved 902 to a horizontal run, curved again to a 902 vertical, and then curved 90Q back to horizontal. The effect is to create turbulence in the fluid flow and distribute the S&W evenly in the flowing stream.
