Methods and treatment fluids for microfracture creation and microproppant delivery in subterranean formations

摘要

Systems, methods, and compositions for creating microfractures within subterranean formations and delivering microproppant particles into microfractures within subterranean formations are provided. In some embodiments, the methods include: providing a treatment fluid that comprises an aqueous base fluid, a surfactant, and a plurality of microproppant particles having a mean particle diameter of about 100 microns or less; introducing the treatment fluid into a subterranean formation at or above a pressure sufficient to initiate the formation of at least one microfracture within the subterranean formation; and allowing at least a portion of the microproppant particles to enter the at least one microfracture within the subterranean formation.
