Title (EN) ENGINEERING PLASTIC/ INORGANIC FIBER BLENDS AS LOST CIRCULATION MATERIALS
(FR) RÉALISATION DE MÉLANGES DE FIBRES PLASTIQUES/INORGANIQUES UTILISÉS COMME DES MATÉRIAUX DE CIRCULATION PERDUE
Abstract: front page image
(EN)A method is disclosed for reducing lost circulation in drilling wells, employing composite materials containing an engineering thermoplastic polymer and mineral fibers. Optionally the composites may also include other components such as calcium carbonate and blending agents.
(FR)L'invention porte sur un procédé de réduction de circulation perdue dans des puits de forage, en utilisant des matériaux composites comportant des fibres minérales et un polymère thermoplastiques industriel. Facultativement, les composites peuvent également comporter d'autres composants tels que le carbonate de calcium et des agents de mélange.
