The Baker Hughes FSA-2 fines stabilization agent is an aqueous solution that, when added to a stimulation treatment in a sandstone formation, minimizes production declines due to fines migration. A hydrolysable organosilane, the FSA-2 agent forms a siloxane covalent bond to reduce the mobility of siliceous fines (quartz, feldspars, mica, clays, etc.) in sandstone formations. An improvement over traditional organosilanes, this additive is pH-balanced to enhance the performance of pH sensitive fluids such as fracturing fluids and acid systems.
