Provide an enhanced performance.
Make chemicals environmentally acceptable.

Sand consolidation is a process involving the injection of a reactive chemical into a naturally unconsolidated formation. The chemical’s purpose is to bind the sand particles that make up the formation matrix while maintaining sufficient permeability to achieve viable production rates.

Various sets of chemistry have been investigated for sand consolidation; among them organosilanes which have demonstrated beneficial effects, such as increased compression strength of the formation. This class of materials can be simply flushed into a formation and do to their ability to rapidly hydrolyze once in contact with aqueous solutions, organosilanes can easily form in-situ silanol species that will condensate with each other and with any other hydroxyl sites on the surface of the mineral particles. This results in a Si-O-Si network that will bind the siliceous material to the formation. Organosilane materials also have been demonstrated to enhance the adhesion and compression performance of organic resins used for consolidating sand formations.

In addition their low bioaccumulation and high biodegradability profile make these chemicals environmentally acceptable.

Dow Corning provides silicon based technology that can chemically bind with the particles and provide an enhance performance. We supply a wide range of organosilanes with different functionalities to address the needs of our customers.
