COMPOSITES FOR USE IN STIMULATION AND SAND CONTROL OPERATIONS

摘要

A composite having a solid particulate and a surface modifying treatment agent on the solid particulate wherein the surface modifying treatment agent has a hydrophobic tail and an anchor for adhering the hydrophobic tail onto the solid particulate. The anchor may be metal and the hydrophobic tail may be an organo-silicon material, a fluorinated hydrocarbon or both an organo-silicon material and a fluorinated hydrocarbon. The composite may be used as a proppant in a hydraulic fracturing operation as well as a sand control particulate in a gravel packing operation. The presence of the surface modifying treatment agent on the surface of the solid particulate reduces the generation of fines and dust as well as the migration of sand during a hydraulic fracturing operation or a sand control operation. The presence of the surface modifying treatment agent on the surface of the solid particulate further enhances the crush resistance of the solid particulate.

1. A composite for treating a well wherein the composite comprises a surface modifying treatment agent at least partially coated onto a solid particulate and wherein the surface modifying treatment agent comprises a metallic anchor and a hydrophobic tail wherein the hydrophobic tail is an organo-silicon material, a fluorinated hydrocarbon or both a hydrophobic organo-silicon material and a fluorinated hydrocarbon and further wherein the metallic anchor of the surface modifying treatment agent is attached to the solid particulate.
