ABSTRACT:
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 formation, 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 silicon tetrahalide, characterized in that the acid formed by the reaction between the silicon polyhalide and the water is neutralized by a neutralizing agent comprising at least one component of the group consisting of alkene oxides, alkenes, alkadienes, alkatrienes and higher alkapolyenes.
