High intergranular/fracture permeability
Web5 de abr. de 2024 · Fluid continuity equation. The fracture apertures increase as long as the fracture propagates and the frac-fluid is injected into the borehole. For the one-dimensional fluid continuity equation, that is, Equation (), the fracture can be subdivided into one-dimensional linear elements (E f in Figure 2).In order to lower the complexity of the … Web3000 appm. The extent of hydrogen-induced intergranular fracture in high-purity nickel depends on the lattice hydro-gen concentration, and the range of hydrogen concentra-tions selected for this study was expected to produce predominantly intergranular fracture [21]. The hydrogen fugacity needed to produce a particular target lattice Fig. 1.
