Title
(EN) LIFTING CONDENSATE FROM WELLBORES
(FR) LEVAGE DE CONDENSAT À PARTIR DE PUITS DE FORAGE
Abstract
(EN)
A vacuum chamber (104) is evacuated by a vacuum pump (102). The vacuum chamber is positioned within a wellbore. A wellbore is fluidically exposed to an interior of the vacuum chamber after the vacuum chamber has been evacuated. At least a portion of condensate within the wellbore is flashed responsive to fluidically exposing a wellbore to an interior of the vacuum chamber.
(FR)
Selon l'invention, une chambre à vide (104) est évacuée par une pompe à vide (102). La chambre à vide est positionnée à l'intérieur d'un puits de forage. Un puits de forage est exposé de manière fluidique à l'intérieur de la chambre à vide après que la chambre à vide a été évacuée. Au moins une partie du condensat à l'intérieur du puits de forage est détendue en réponse à l'exposition fluidique d'un puits de forage à l'intérieur de la chambre à vide.
