Abstract

On stimule l'écoulement descendant dans un puits de gaz naturel au moyen d'un compresseur de fond rotatif à plusieurs étages (10), actionné par un moteur électrique (6). De préférence, l'arbre (9) du compresseur est équipé de paliers de tourillon à gaz (12), le moteur est un moteur à aimant permanent sans balais qui est susceptible de fonctionner à une vitesse de 5000 tours/mn et qui entraîne directement l'arbre (9) du compresseur, et la colonne de production est thermiquement isolée par suppression de l'espace annulaire environnant.
