Sand in unconsolidated subterranean formations causes problems in oil recovery, which can be overcome by a method of consolidating sand in a subterranean formation, which method comprises: (i) contacting said sand in a first location in the presence of water with a slurry in a liquid medium of cement of average particle size less than 10 microns to produce in said medium a mixture comprising sand, water and some of the cement, and a remainder comprising the rest of the cement, (ii) preferably separating from said location said remainder from said mixture, (iii) which mixture is allowed to set to give permeable consolidated sand.

Le sable, dans les formations souterraines non consolidées, pose problème dans le cadre de l'extraction du pétrole, cela pouvant être surmonté par un procédé consistant à consolider le sable dans une formation souterraine, ledit procédé comprenant les étapes consistant à (i) mettre en contact ledit sable, au niveau d'un premier emplacement et en présence d'eau, avec une suspension dans un milieu liquide de ciment d'une taille de particule moyenne inférieure à 10 microns pour produire, dans ledit milieu, un mélange comprenant du sable, de l'eau et un peu de ciment, ainsi qu'un reliquat comprenant le reste du ciment, (ii) séparer, de préférence, dudit emplacement ledit reliquat dudit mélange, (iii) et laisser prendre ledit mélange pour obtenir du sable perméable consolidé.
