Title (EN) WELL KICKOFF SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE REDÉMARRAGE DE PUITS
Abstract:
(EN) Systems (10) and methods for removing fluid from a subterranean well (12) with a fluid removal system includes lowering an elongated member (26) into tubing (20) of the subterranean well (12) to a lower position, the elongated tubing having a plunger (29) or valve body (28) located at an end, wherein fluid passes past the plunger or through a valve opening (32) as the valve body moves into the subterranean well. The plunger or valve body (28, 29) is moved in a direction out of the subterranean well (12) so that fluid cannot pass the plunger or through the valve opening, moving the fluid out of the subterranean well.
(FR) L'invention concerne des systèmes (10) et procédés d'extraction de fluide à partir d'un puits souterrain (12) à l'aide d'un système d'extraction de fluide, consistant à descendre un élément allongé (26) dans un tubage (20) du puits souterrain jusqu'à une position inférieure, le tube allongé comprenant un piston (29) ou corps de soupape (28) situé à une extrémité, le fluide passant au-delà du piston ou à travers une ouverture de soupape (32) lorsque le corps de soupape est déplacé dans le puits souterrain. Le piston ou le corps de soupape (28, 29) est déplacé dans une direction hors du puits souterrain (12) de telle sorte que le fluide ne peut pas passer au delà du piston ou à travers l'ouverture de soupape, déplaçant le fluide hors du puits souterrain.
