Proppant is a key material for enhancing unconventional oil and gas production which requires a long distance of migration and efficient liquid conductivity paths within the hydraulic fracture.However,it is difficult to find a proppant with both high self-suspension ability and liquid conductivity.Here,a simple method is developed to coat epoxy resin onto the ceramic proppant and fabricate a novel coated proppant with high hydrophobicity,self-suspension,and liquid conductivity performance.Compared with uncoated ceramic proppants,the epoxy resin coated (ERC) proppant has a high self-suspension ability nearly 16 times that of the uncoated proppants.Besides,the hydrophobic property and the liquid conductivity of the ERC proppant increased by 83.8% and 16.71%,respectively,compared with the uncoated proppants.In summary,this novel ERC proppant provides new insights into the design of functional proppants,which are expected to be applied to oil and gas production.
