Formation damage associated with fines migration has often contributed to rapid production declines and short-lived stimulation successes. Although clay migration and stabilization have been discussed in various papers through the years, the non-clay siliceous fines stabilization has received little attention. A recently developed fines stabilizing method is utilized to reduce or prevent the migration of both clay and non-clay siliceous fines. This method utilizes an organosilane additive which reacts in situ to stabilize potentially mobile siliceous fines. This paper describes the use of and the mechanism by which the organosilane additive stabilizes fines. The laboratory data and field case histories further discuss the beneficial effects of employing organosilane as a fines stabilizing agent.
