CA 2552422
Sand and other particulate metal oxide-containing solids are often difficult to handle and process due to their inability to aggregate. A method for treating solid materials is disclosed, where the treating compositions coats surfaces or portions of surfaces of the solid materials changing an aggregation or agglomeration propensity of the materials. An acidifying agent and a surface modifying agent are present in a composition applied to the solid materials. Treated solid materials are also disclosed. The methods and treated materials are ideally suited for oil field applications.
Le sable et les autres solides renfermant des particules d'oxydes de métaux sont souvent difficiles à manipuler et à traiter en raison de leur incapacité à s'agglutiner. On divulgue une méthode pour le traitement des matières solides, par laquelle des compositions de traitement recouvrent la surface ou une partie de la surface des matières solides pour modifier la propension de celles-ci à s'agréger ou à s'agglomérer. Une composition renfermant un agent acidifiant et un agent de surface est appliquée sur les matières solides. Les matières solides traitées sont elles aussi divulguées. Les méthodes et les matières traitées conviennent parfaitement à des applications dans les champs pétrolifères.
