Abstract: A composite is characterized by particulates of sand wherein at least a portion of the surface of the particulates is coated with a polycationic polymer. The presence of the polycationic polymer on the surface of the particulates reduces the amount of dust generated during handling and use of the sand. The polycationic polymer further reduces the amount of dust generated during transport of the sand as well during manufacture, treatment or processing of the sand.

Abstract: A well treatment fluid contains a surface modifying treatment agent having an anchor and a hydrophobic tail. The surface modifying treatment agent is an organophosphorus acid derivative. After the well treatment fluid is pumped into a well penetrating the subterranean formation, the anchor binds to the surface of the formation. The subterranean formation is a siliceous formation or a metal oxide-containing subterranean formation. The anchor bonds to a Si atom when the formation is a siliceous formation and to the metal of the metal oxide when the formation is a metal oxide-containing formation. After being bound to the surface of the formation, frictional drag within the well is reduced. This allows for faster recovery of formation fluids. The bonding of the surface modifying treatment agent onto the formation may further be enhanced by first pre-treating the formation with a non-aqueous fluid. By increasing the number of sites for the surface modifying treatment agent to bind onto the surface of the subterranean formation, productivity is improved.

Abstract translation: 良好的处理流体包含具有锚和疏水尾部的表面改性处理剂。 表面改性处理剂是有机磷酸衍生物。 在井处理流体被泵入穿透地下地层的井中之后，锚固体结合到地层的表面。 地层是硅质地层或含金属氧化物的地下地层。 当形成为含硅金属的地层时，当形成为含金属氧化物的地层时，锚定物与Si原子结合，并与金属氧化物的金属键合。 在结合到地层的表面之后，井内的摩擦阻力减小。 这使得地层流体的回收更快。 通过首先用非水性流体预处理地层，可以进一步增强表面改性处理剂与地层的结合。 通过增加用于表面改性处理剂结合到地层表面上的位点数量，提高了生产率。

Abstract: 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.
