Abstract

During injection of fracture fluid into a subterranean formation, the bottomhole treating pressure at which the change in pressure is essentially zero is determined. This pressure is the maximum which should be attained for that formation during fracture and is useful for designing subsequent fracture treatments within the same subterranean formation.
