Title (EN) USE OF CROSSLINKED POLYMER SYSTEM FOR MITIGATION OF ANNULAR PRESSURE BUILDUP
(FR) UTILISATION DE SYSTÈME DE POLYMÈRE RÉTICULÉ POUR L'ATTÉNUATION DE L'ACCUMULATION DE PRESSION ANNULAIRE
Abstract:
(EN) A method of mitigating annular pressure buildup includes providing or using a foamed treatment fluid including : an aqueous base fluid; a water- soluble polymer comprising carbonyl groups; an organic crosslinking agent that comprises an amine group that is capable of crosslinking the water-soluble polymer comprising carbonyl groups; a foam surfactant; and sufficient gas to form a foam; and introducing the foamed treatment fluid into a well bore annulus. A foamed treatment fluid includes an aqueous base fluid; a water- soluble polymer comprising carbonyl groups; an organic crosslinking agent that comprises an amine group that is capable of crosslinking the water-soluble polymer comprising carbonyl groups; a foam surfactant; and sufficient gas to form a foam.
(FR) La présente invention concerne un procédé d'atténuation de l'accumulation de pression annulaire comportant la fourniture ou l'utilisation d'un fluide de traitement sous forme de mousse comprenant : un fluide de base aqueux ; un polymère soluble dans l'eau comprenant des groupes carbonyle ; un agent de réticulation organique qui comprend un groupe amine qui est apte à réticuler le polymère soluble dans l'eau comprenant des groupes carbonyle ; un tensioactif de mousse ; et une quantité suffisante de gaz pour former une mousse ; et l'introduction du fluide de traitement sous forme de mousse dans un espace annulaire de puits de forage. Un fluide de traitement sous forme de mousse comprend un fluide à base aqueux ; un polymère soluble dans l'eau comprenant des groupes carbonyle ; un agent de réticulation organique qui comprend un groupe amine qui est apte à réticuler le polymère soluble dans l'eau comprenant des groupes carbonyle ; un tensioactif de mousse ; et une quantité suffisante de gaz pour former une mousse.
