Web6.2.4 Minimum stress from diagnostic fracture injection test. The DFIT is another method to determine the closure pressure (e.g., Martin et al., 2012). It can be used to discern both hydraulic fracturing character and the reservoir pressure. It is often performed before the stimulation treatment of a formation. WebSep 9, 2015 · A hydraulic fracture is a pressure-induced fracture caused by injecting fluid into a target rock formation. Fluid is pumped into the formation at pressures that exceed the fracture pressure—the pressure at which rocks break.
