"This dissertation discusses two separate, yet inter-related studies. The first study was an extension of historical work comparing transversely fractured versus longitudinally fractured horizontal wells in multiphase flow environment. The second study investigated hydraulic fracture complexities and the benefits of maximizing or minimizing complexities in unconventional resources and tight reservoirs.
The main objective of this research was to investigate fracture complexity and its impact on well performance and economics. To achieve that objective, three different integrated completions and reservoir models were built. Two of the three models, a hybrid reservoir model and micro-seismic based SRV (stimulated reservoir volume) model, were built to capture presences of discrete fracture networks (DFN). The results of the DFN-based models were compared to an integrated planar fracture model, which had bi-wing fractures with limited or no fracture complexity. The second objective of this research was to determine reservoir permeability based cut-off criterion that can be used as guide when selecting whether to drill transversely fractured versus longitudinally fractured horizontal wells in multiphase flow environment. The reservoir models built for the multiphase flow would also investigate the effects of stress dependent permeability, adsorption gas and non-Darcy flow effect.
The third objective of this research was to develop a calibrated hydraulic fracture and reservoir model for the Montney shale, particularly for the Upper Montney Formation. This model would help companies select best lateral placement options in the Upper Montney, stage perforation targets and model-based stage spacing"--Abstract, page iii.
