Interfaces are recognized to a be major in-situ layered reservoir realities that are challenging the oil and gas industry. Their impact on the hydraulic fracture vertical growth is well established and yet their properties are difficult to assess with the current limited data. The purpose of this analysis is to estimate the hydraulic fracture vertical growth in layered rock while focusing on the heterogeneous interfaces properties. The model combines deterministic tools based on the Material Point Method (MPM) geomechanical model which includes interface modeling tools with a stochastic description of the interfaces in the geomechanical model. Combining this modeling capability with the Monte Carlo simulations, makes it possible to propagate the uncertainty of the interface properties to resulting fracture heights. The model shows a large difference of fracture heights in the presence of interfaces. The analysis demonstrated the ability of the model to capture the range of uncertainties in hydraulic fracture heights that can be input in probabilistic frac design and analysis software.
