Methods of contacting a subterranean formation are described which provide improved control or reduction of particulate migration, transport or flowback in wellbores and reservoirs, and which may do so without sacrificing substantial hydraulic conductivity. One method comprises injecting into a well-bore intersecting the subterranean formation a fluid composition comprising a first component and a second component dispersed in a carrier fluid, at least a portion of the first component or second component being provided as at least one multicomponent article having an aspect ratio greater than 1:1.1; forming a network comprising the first component; and binding the network with the second component.
L'invention concerne des procédés d'accès à une formation souterraine qui assurent un contrôle ou une réduction améliorés de la migration, du transport ou du retour des matières particulaires dans les trous de forage et les réservoirs, et ce sans perte substantielle en conductivité hydraulique. Un procédé consiste à injecter dans un trou de forage en intersection avec la formation souterraine une composition fluide comprenant un premier composant et un second composant dispersés dans un fluide porteur, au moins une partie du premier composant ou du second composant étant constituée par au moins un article à plusieurs composants dont le rapport longueur/diamètre est supérieur à 1:1,1 ; former un réseau comprenant le premier composant ; et lier le réseau au second composant.
