Title
(EN) CASING FLUSH FLUID, RECYCLABLE CLEANOUT FLUIDS, AND APPLICATIONS THEREOF
(FR) FLUIDE DE RINÇAGE DE TUBAGE, FLUIDES DE NETTOYAGE RECYCLABLES, ET APPLICATIONS ASSOCIÉES
Abstract
(EN)
A method of removing residual proppant from a bottom of a casing after a fracturing operation comprises: circulating a casing flush fluid comprising a carrier and a superabsorbent polymer in the casing; and transporting the residual proppant from the bottom of the casing to a fracture created by a hydraulic fracturing operation. A method for cleaning a wellbore comprises: introducing a cleanout fluid through a conduit inserted into the wellbore, the cleanout fluid comprising a carrier fluid and a superabsorbent polymer; and receiving a returning fluid comprising debris at the surface of the wellbore from an annular space between the conduit and a wall of the wellbore.
(FR)
Un procédé d'élimination d'agent de soutènement résiduel d'un fond d'un tubage après une opération de fracturation consiste à : faire circuler dans le tubage un fluide de rinçage de tubage comprenant un transporteur et un polymère superabsorbant ; et transporter l'agent de soutènement résiduel depuis le fond du tubage vers une fracture créée par une opération de fracturation hydraulique. Un procédé de nettoyage d'un puits de forage consiste à : introduire un fluide de nettoyage à travers un conduit inséré dans le puits de forage, le fluide de nettoyage comprenant un fluide transporteur et un polymère superabsorbant ; et recevoir un fluide de retour comprenant des débris à la surface du puits de forage depuis un espace annulaire entre le conduit et une paroi du puits de forage.
