A B S T R A C T METHOD FOR INCREASING THE BONDING STRENGTH BETWEEN GRAINS IN A SUBSURFACE FORMATION ZONE Method for increasing the bonding strength between grains in a subsurface formation zone with water-wet pore space walls, and located adjacent to a well penetrating said forma- tion, wherein silicon polyhalide in a dry carrier fluid is passed into the said zone, the silicon polyhalide having a water reactivity substantially equal to that of siliccn tetrahalide. The acid formed by the reaction between the silicon polyhalide and the water is neutralised by a neutralising agent comprising at least one component of the group consisting of alkene oxides, alkenes, alkadienes, alkatrienes and higher alkapolyenes.
