Title
(EN) ELECTRIC SUBMERSIBLE PUMP WITH DISCHARGE RECYCLE
(FR) POMPE ÉLECTRIQUE IMMERGÉE À RECYCLAGE DU REFOULEMENT
Abstract
(EN)
Included are electric submersible pump assemblies, methods of use, and systems incorporating said electric submersible pump assemblies. An example electric submersible pump assembly comprises an electric submersible pump comprising a pump intake, a storage chamber in fluid communication with the discharge side of the electric submersible pump, and a tubing configured to allow for fluid communication between the pump intake and the storage chamber such that fluid may flow from the storage chamber into the pump intake.
(FR)
Cette invention concerne des ensembles pompes électriques immergées, des procédés d'utilisation et des systèmes incorporant lesdits ensembles pompes électriques immergées. Un mode de réalisation cité à titre d'exemple d'ensemble pompe électrique immergée comprend une pompe électrique immergée comprenant une entrée de pompe, une chambre de stockage en communication fluidique avec le côté refoulement de la pompe électrique immergée, et un tube configuré pour permettre une communication fluidique entre l'entrée de pompe et la chambre de stockage de telle sorte que le fluide puisse s'écouler de la chambre de stockage à l'entrée de pompe.
