Conventional models of hydraulic fracture closure make assumptions about the fracture geometry and rock mechanical behavior. In this paper we present the results of scaled laboratory experiments. We show that deviations from conventional assumptions influence leak-off volumes, mechanical behavior, and pressure decline significantly. We discuss mechanisms that lead to these deviations from assumptions during fracture closure.
