Abstract

La présente invention concerne un système de préparation de puits unique comprenant une structure de base (8) à travers laquelle le puits est foré et complété à l'aide d'une tête de puits (6). Un module d'arbre de Noël récupérable (10) contenant un arbre de Noël (12) relié à un connecteur de tête de puits (14) est monté sur la structure de base (8) par le connecteur de tête de puits (14) de façon à recevoir le liquide de puits en provenance de la tête de puits. Le module précité (8) contient deux séparateurs de traitement de liquide (16) destinés à traiter le liquide de traitement en provenance du puits via la tête de puits (6) et l'arbre de Noël (12). Dans un mode de réalisation modifié, des modules supplémentaires sont montés sur la structure de base, chacun d'eux comprenant un séparateur de traitement de liquide (16), et le module d'arbre de Noël dirigeant le liquide de production vers les séparateurs via la structure de base (8).
