Abstract
A technique is provided to control flow in subterranean applications, such as hydrocarbon fluid production applications. The technique utilizes an aggregate formed, at least in part, of particles that swell in the presence of a specific substance or substances. The aggregate is deployed as a slurry or in other forms to desired subterranean locations. Once located, the aggregate allows the flow of hydrocarbon fluids but swells upon contact with the specific substance or substances to limit inflow of undesirable fluids.
