Title (EN) CELLULOSE NANOWHISKERS IN WELL SERVICES
(FR) NANOCRISTALLITES DE CELLULOSE DANS DES PRÉPARATIONS DE PUITS
Abstract:
(EN) A method is provided for use in various well services, the method including the steps of: (a) forming or providing a well fluid comprising cellulose nanowhiskers; and (b) introducing the well fluid into a well. The method can be used, for example, for increasing the strength of a cement, for increasing the viscosity of a water-based well fluid, such as for a kill pill, a fracturing fluid, a gravel packing fluid.
(FR) La présente invention concerne un procédé destiné à être utilisé lors de diverses préparations de puits, le procédé comprenant les étapes consistant à : (a) former ou fournir un fluide de puits comprenant des nanocristallites de cellulose ; et (b) introduire le fluide de puits dans un puits. Le procédé peut être utilisé, par exemple, pour augmenter la résistance d'un ciment, pour augmenter la viscosité d'un fluide de puits à base d'eau, notamment pour un bouchon d'injection, une boue de fracturation, un fluide de filtres à graviers.
