  • Publication number: 20210017443
    Abstract: Methods for treating a subterranean formation using treatment fluids including a weakly emulsifying surfactant are provided. In one or more embodiments, the methods include introducing a first treatment fluid comprising a base fluid and a weakly emulsifying surfactant into a first wellbore penetrating at least a first portion of a subterranean formation; and introducing a second treatment fluid into a second wellbore penetrating at least a second portion of the subterranean formation at a pressure sufficient to create or enhance one or more fractures extending from the second wellbore into the subterranean formation.
