Title (EN) PHASE TRANSFER FOR THE PREPARATION OF STABLE NANO-SCALE ORGANOSOLS
(FR) TRANSFERT DE PHASE DESTINÉ À LA PRÉPARATION D'ORGANOSOLS NANOMÉTRIQUES STABLES
Abstract:
(EN) A method for preparing concentrated and stable nanoparticle organosols using phase transfer is disclosed. The method includes transferring nanoparticles from a hydrosol into a hydrocarbon carrier with the aid of a transfer agent. The transfer agent can be added before, during or after the reaction of nanoparticle preparation and can be added to the aqueous or the organic carrier. The nanoparticles may be prepared in situ, pre-prepared in-house or commercially available. At the optimum values of the different parameters; namely precursor concentrations, amount of transfer agent and concentration of nanoparticles in the organosol, complete transfer of the nanoparticles may be achieved. The approach employs room temperature, moderate mixing and minimum number and quantity of chemicals relative to prior art. The nanoparticles may be used in fluids used in oil and gas recovery including drilling, completion, and stimulation fluids.
(FR) L'invention concerne un procédé de préparation d'organosols de nanoparticules concentrés et stables au moyen d'un transfert de phase. Le procédé consiste à transférer des nanoparticules d'un hydrosol à un véhicule hydrocarboné à l'aide d'un agent de transfert. L'agent de transfert peut être ajouté avant, pendant ou après la réaction de préparation des nanoparticules, et peut être ajouté au véhicule aqueux ou organique. Les nanoparticules peuvent être préparées in situ, préalablement préparées en interne ou disponibles dans le commerce. Aux valeurs optimales des différents paramètres, à savoir les concentrations de précurseur, la quantité d'agent de transfert et la concentration de nanoparticules dans l'organosol, un transfert complet des nanoparticules peut être obtenu. L'approche utilise la température ambiante, un mélange modéré et un nombre et une quantité minimum de produits chimiques par rapport à l'état de la technique. Les nanoparticules peuvent être utilisées dans des fluides utilisés dans la récupération de pétrole et de gaz, y compris des fluides de forage, de complétion et de stimulation.
