Title (EN) CROSS-LINKED LEVAN BLENDS AS LOST CIRCULATION MATERIALS
(FR) MÉLANGES DE LÉVANE RÉTICULÉS UTILISÉS COMME MATÉRIAUX DE PERTE DE CIRCULATION
Abstract:
(EN) The present invention is directed to compositions and methods for reducing lost circulation in drilling wells with compositions preferably comprising cross linked levan and calcium carbonate mixed with clay minerals such as kaolinite and other minerals blends or salts thereof.
(FR) La présente invention concerne des compositions et des procédés pour réduire la perte de circulation dans des puits de forage avec des compositions comprenant de préférence du lévane réticulé et du carbonate de calcium mélangés à des minéraux argileux tels que la kaolinite et d'autres mélanges minéraux ou des sels de ceux-ci.
