Abstract: A technique facilitates a well treatment, such as a well stimulation. The technique comprises injecting a gel containing proppant into a wellbore extending into a subterranean formation. Additionally, a low viscosity fluid is injected into the wellbore with the gel either simultaneously or separately. An additive or additives may be used to maintain the gel in the low viscosity fluid. The technique further comprises separating the gel into slugs and then causing the slugs to flow into fractures in the subterranean formation.
