Title (EN) NANO-CARBOHYDRATE COMPOSITES AS A LOST CIRCULATION MATERIALS - LCM ORIGAMI AND OTHER DRILLING FLUID APPLICATIONS
(FR) NANO-COMPOSITES DE CARBOHYDRATES EN TANT QUE MATÉRIAUX DE PERTE DE CIRCULATION - LCM ORIGAMI ET AUTRES APPLICATIONS DE FLUIDE DE FORAGE
Abstract: front page image
(EN)A wellbore treatment fluid containing lost circulation materials and methods for using the treatment fluid, the fluid including a carrier fluid and nano-carbohydrate based sheets. The sheets may be folded or rolled into various cross-sectional surface area reducing configurations. The nano- carbohydrate based sheets may contain cellulose and or chitin materials. A method for utilizing the treatment fluid for creation or maintenance of a well includes forming or providing the treatment fluid and introducing the treatment fluid into a borehole.
(FR)L'invention concerne un fluide de traitement de puits de forage contenant des matériaux de perte de circulation et des procédés d'utilisation du fluide de traitement, le fluide incluant un fluide support et des nano-feuilles à base de carbohydrates. Les feuilles peuvent être pliées ou roulées dans diverses configurations réduisant l'aire de surface transversale. Les nano-feuilles à base de carbohydrates peuvent contenir des matériaux de cellulose et/ou de chitine. L'invention concerne un procédé d'utilisation du fluide de traitement pour créer ou maintenir un puits qui inclut la formation ou la fourniture du fluide de traitement et l'introduction du fluide de traitement dans un trou de forage.
