Engineering design of hydraulic fracturing proppants typically focuses on maximizing permeability retention under stress, resistance to high temperatures, and controlling properties such as specific gravity and particle size; less attention is paid to the proppant's wetting characteristics and their potential impact on the deliverability of a hydraulic fracture. The purpose of this work is to investigate the effect of proppant wettability on the conductivity of hydraulic fractures through laboratory measurements. Results demonstrate a competing effect between permeability and wettability, the latter having a diminished impact on displacement efficiency at high permeability values.
