Avant l'essai, Cestoil et l'op\u00e9rateur se sont mis d'accord sur la configuration de pompage, les limites du traitement et les modalit\u00e9s d'\u00e9valuation des performances. La question cl\u00e9 \u00e9tait de savoir si la conduite trait\u00e9e pouvait assurer un d\u00e9bit sup\u00e9rieur dans les conditions d'exploitation convenues, tout en enregistrant la r\u00e9ponse en pression et l'injection de produits chimiques parall\u00e8lement au d\u00e9bit.<\/p><\/div><\/section><section class=\"ccr-section\" id=\"case-section-2\"><h2>Le r\u00f4le du Cestoil CDR2081<\/h2><div><p>Le CDR2081 est un r\u00e9ducteur de tra\u00een\u00e9e \u00e0 base de polyol\u00e9fines d\u00e9velopp\u00e9 Cestoil .
