Abstract
Une méthode de pompage peut comprendre le déplacement dun train de tiges au moyen dune pression dune source de pression sur un actionneur, y compris un accumulateur et un volume de gaz séparé en communication avec laccumulateur. Un détecteur indique la présence dun fluide dans le volume de gaz. Un système de pompage peut comprendre un actionneur, une pompe connectée entre lactionneur et un accumulateur, un fluide hydraulique contactant un gaz dans laccumulateur, un volume de gaz séparé en communication avec laccumulateur et un détecteur qui détecte le fluide hydraulique dans le volume de gaz. Un autre système de pompage peut comprendre un actionneur, une pompe connectée entre lactionneur et un accumulateur, un fluide hydraulique contactant un gaz dans laccumulateur qui reçoit de lazote gazeux dun appareil concentrateur dazote pendant que le fluide hydraulique circule entre la pompe et lactionneur, un volume de gaz séparé en communication avec laccumulateur et un détecteur qui détecte le fluide hydraulique dans le volume de gaz.
