An aqueous slurry composition for use in industries such as petroleum and pipeline industries that includes: a particulate, an aqueous carrier fluid, a chemical compound that renders the particulate surface hydrophobic, and a small amount of an oil. The slurry is produced by rendering the surface of the particulate hydrophobic during or before the making of the slurry. The addition of the oil greatly enhances the aggregation potential of the hydrophobically modified particulates once placed in the well bore.
L'invention concerne une composition de boue aqueuse destinée à être utilisée dans des industries telles que les industries du pétrole et des pipelines, laquelle comprend : une matière particulaire, un fluide véhicule aqueux, un composé chimique qui rend la surface de la matière particulaire hydrophobe et une petite quantité d'une huile. On produit la boue en rendant la surface de la matière particulaire hydrophobe au cours de la fabrication de la boue ou avant celle-ci. L'ajout de l'huile augmente fortement le pouvoir d'agrégation de la matière particulaire modifiée de manière hydrophobe une fois placée dans le puits de forage.
