puits horizontal

OBS: Selon certains auteurs, le terme «puits horizontal» correspond au segment du puits de forage qui s'écarte d'au moins 80 degrés de la verticale.

CONT: Based on curvature rate, the most commonly used classification for types of horizontal wells are as follows: ultra-short radius, short radius, medium radius and long radius.
OBS: In a horizontal well, the horizontal extension is that part of the wellbore beyond the point where it first deviates by 80 degrees or more from vertical.
