Abstract

L'invention concerne un système destiné à l'extraction de pétrole brut. Le système comprend un arbre principal et une ou plusieurs dérivations horizontales qui font saillie depuis la base de l'arbre principal, disposées adjacentes à un piège de réservoir ou à une formation pétrolière, ou juste en dessous. Plusieurs trous de forage de produit sont forés depuis la dérivation horizontale en direction du piège de réservoir pour collecter le mélange de pétrole et le diriger de manière à en assurer l'écoulement, soit par gravité soit grâce à la pression du réservoir à un certain angle vers les dérivations sous la formation. Un collecteur ou un système de distribution disposé dans une ou plusieurs dérivations horizontales collectent le flux provenant de plusieurs trous de forage de production. Le flux collecté est soit pompé soit remonté à la surface à des fins de séparation, de traitement et/ou de transformation; il peut aussi être traité avant d'être pompé ou remonté à la surface.
