A new chart of hydraulic fracture height prediction based on fluid–solid coupling equations and rock fracture mechanics [PDF]
Royal Society Open Science, 2018 The conventional method to predict hydraulic fracture height depends on linear elastic mechanics, and the typical Gulrajani–Nolte chart fails to reflect fracture height when the net pressure in the fracture is too high.
