  Fouling caused by contaminants onto a metallic tubular, flow conduit or vessel in an underground reservoir or extending from or to an underground reservoir may be inhibited by applying onto the surface of the metallic tubular, flow conduit or vessel a treatment agent comprising a hydrophobic tail and an anchor. The anchor attaches the treatment agent onto the surface of the metallic tubular, flow conduit or vessel.

  A method for recovering hydrocarbon material from a subterranean formation includes introducing a treatment fluid into the subterranean formation. One treatment fluid includes at least one organometallic material having a metal or metalloid from Group III of the Periodic Table or a transition metal. An optional second fluid having an organophosphorous material can also be introduced. Another treatment fluid includes the reaction product of a transition metal compound and a silicon-containing material.

  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 is an organophosphorus acid derivative. 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.

  一种具有固体微粒和固体微粒表面改性处理剂的复合材料，其中表面改性处理剂具有疏水尾部和用于将疏水尾部粘附到固体微粒上的锚。锚是一种有机磷酸衍生物。这种复合材料既可用作水力压裂作业中的支撑剂，也可用作砾石填料作业中的防砂颗粒。固体微粒表面含有表面改性处理剂，可减少水力压裂作业或防沙作业中细粒和粉尘的产生以及沙子的迁移。固体颗粒表面的表面改性处理剂可进一步增强固体颗粒的抗压性。
