Title (EN) METHODS AND COMPOSITIONS OF IMPROVING WELLBORE CLEANOUT TREATMENTS
(FR) PROCÉDÉS ET COMPOSITIONS POUR AMÉLIORER LES TRAITEMENTS DE NETTOYAGE DES TROUS DE FORAGE
Abstract: front page image
(EN)Methods of performing a cleanout treatment including providing a wellbore in a subterranean formation having unconsolidated particulates therein; providing a treatment fluid comprising an aqueous base fluid and a hydrophobically modified flocculating water-soluble polymer; introducing the treatment fluid into the wellbore in the subterranean formation; flocculating at least a portion of the unconsolidated particulates by exposure to the hydrophobically modified flocculating water-soluble polymer; removing the treatment fluid comprising the flocculated unconsolidated particulates from the wellbore in the subterranean formation.
(FR)Cette invention concerne des procédés de mise en œuvre d'un traitement de nettoyage comprenant la préparation d'un trou de forage dans une formation souterraine contenant des matières particulaires non consolidées ; l'utilisation d'un fluide de traitement comprenant un fluide de base aqueux et un polymère floculant hydrosoluble modifié pour être hydrophobe ; l'introduction du fluide de traitement dans le trou de forage dans la formation souterraine ; la floculation d'au moins une partie des matières particulaires non consolidées par exposition au polymère floculant hydrosoluble modifié pour être hydrophobe ; et l'enlèvement du fluide de traitement comprenant les matières particulaires non consolidées floculées du trou de forage dans la formation souterraine.
