Stimulated reservoir volume (SRV) is fundamentally the network of fractures induced during hydraulic fracturing. The volume created by hydraulic fracturing is referred to as the stimulated reservoir volume (SRV) and is used as a correlation parameter for well performance (Mayerhofer et al., 2010). Most analyses are focused on the induced primary fracture and not the ensemble of fractures created. The uncertainty that arises in the dimensions of SRV is caused mainly by the complexity of the fracture network and our inability to directly observe it. Most models of hydraulic fractures only take the primary fractures into consideration, which dismisses the secondary fracture network entirely. This research illustrates that secondary microfractures can triple the stimulated area and pore connections within a reservoir. As the demand for reservoir stimulation increases, efforts are being directed towards quantifying microfractures to determine how they impact reservoir production.
