Abstract
Techniques for hydraulically fracturing a geologic formation include circulating a proppant-free hydraulic fracturing liquid into a wellbore that is formed from a terranean surface into a geologic formation within a subterranean zone that is adjacent the wellbore; fluidly contacting the geologic formation with the proppant-free hydraulic fracturing liquid for a specified duration of time; and subsequent to the specified duration of time, circulating a hydraulic fracturing liquid that includes proppant into the wellbore to fracture the geologic formation.
