Title (EN) METHOD OF MAKING ROD-SHAPED PARTICLES FOR USE AS PROPPANT AND ANTI-FLOWBACK ADDITIVE
(FR) PROCÉDÉ DE FABRICATION DE PARTICULES EN FORME DE TIGE DESTINÉES À ÊTRE UTILISÉES COMME AGENT DE SOUTÈNEMENT ET ADDITIFS ANTI-RETOUR
Abstract:
(EN) A method for forming rod-shaped particles includes reducing a length of rods derived from a slurry made up of particles and a reactant, wherein the rods are in a stabilized state in which the reactant has been at least partially reacted with a coagulant, but the rods have not been sintered, and subsequently sintering the reduced length stabilized rods. The reducing the length of the stabilized rods includes subjecting the stabilized rods to mechanical vibration applied by a device, or feeding the stabilized rods through a device having a rotating cutting mechanism.
(FR) Un procédé pour former de particules en forme de tiges consiste à réduire une longueur de tiges dérivées d'une suspension épaisse constituée de particules et d'un réactif, les tiges étant dans un état stabilisé dans lequel le réactif a été au moins partiellement amené à réagir avec un coagulant, mais les tiges n'ont pas été frittées, et par la suite à fritter les tiges stabilisées de longueur réduite. La réduction de la longueur des tiges stabilisées consiste à soumettre les tiges stabilisées à une vibration mécanique appliquée par un dispositif, ou à introduire les tiges stabilisées à travers un dispositif ayant un mécanisme de coupe rotatif
