Methods of hydraulic fracturing

A method of hydraulic fracturing comprising:

• pumping a hydraulic fracturing fluid through a wellbore into a subsurface formation, in which the hydraulic fracturing fluid comprises a plurality of proppants in which individual proppants of the plurality of proppants travel a first distance into the subsurface formation and have a persistent diameter homogeneity;
• shutting in the wellbore to facilitate crushing individual proppants under formation pressure to form microproppants;
• and
• resuming pumping the hydraulic fracturing fluid after crushing individual proppants and forcing the microproppants to a second distance within the subsurface formation, in which:
• the second distance is beyond the first distance relative to the wellbore;
• and
• forcing the microproppants to a second distance within the subsurface formation comprises forcing the microproppants into microfractures within the subsurface formation.
