Webb14 nov. 2024 · Hydraulic fracturing is a process of injecting a large volume of water, chemical, and sand at a high rate and pressure into a target formation, causing deformation and failure (fracture) of the rock mass and increasing the permeability in a region surrounding the injection point (Fig. 1a). WebbThe gas compositions of the fingerprinted geologic intervals were therefore employed as a constraint on fracture height growth, estimated in the model to be 175 ft (53 m, propped height). However, because of the uncertainty in model input parameters, a stochastic approach was required to derive a range in hydraulic fracture properties.
