A shale-stabilizing additive is described which comprises a copolymer of an olefinically unsaturated hydrocarbon and an ethylenically unsaturated carboxylic acid, carboxylic acid salt or carboxylic acid anhydride with alkylene oxide based side chains. The additive can be used for water-based service fluids (WBM) to facilitate the drilling or completion process in shales or clayey formations.
On décrit un additif de stabilisation de formations schisteuses, qui comprend un copolymère d'hydrocarbure alcénique et d'acide carboxylique éthyléniquement insaturé, un sel d'acide carboxylique ou un anhydride d'acide carboxylique présentant des chaînes latérales à base d'oxyde d'alkylène. Cet additif peut être utilisé pour des fluides industriels à base aqueuse (WBM) pour faciliter le processus de foration ou de complétion dans des formations schisteuses ou argileuses.
