... Abstract The objective of this paper is to improve the evaluation and characterization of the fracture network as well as the production matching in the Horn River Shale of Canada. The task is carried out by extending the hybrid hydraulic fracture (HHF) model introduced by Urban et al. (2017...

... natural fractures, fissures, and microfractures plays a significant role on generation of induced hydraulic fractures. Therefore, much more attention should be paid to the model development of DFIT complexity. In previous work, Chen et al. (2017a) built a complex fracture-network model for after...

... valid for the flow in some tight sands with very low permeability but no well-developed fracture networks, except for a quite small η i . However, this isn't the case for the unconventional reservoirs with complex fracture systems. By the assumptions, all the produced fluid comes directly from...

... Abstract This study aims to study the driving mechanism of proppant transport from wellbore to hydraulic fracture networks (HFN) by fracturing fluid, using computational fluid dynamics (CFD). We simulated multiphase slurry flow containing proppant based on the Euler-Euler multiphase flow model...

... . Abstract It is generally believed that creating a Stimulated Rock Volume (SRV) is a good thing. Completion engineers talk about creating complexity, geologists talk about stimulating a natural fracture network, geomechanicists highlight the importance of low stress anisotropy. But how much do...

This is accomplished using advanced interpretation methods that include discrete fracture network modeling and propped stimulated reservoir volume estimates. Analysis shows that the presence of a preexisting...

Understanding the impact of seismically-visible, planar, structural features (e.g. faults or lineaments) proved to be more problematic...

However, the effective fracture network is actually an open system which allows fluid influx from the surrounding...

... Abstract Hydraulic fracturing in shale gas reservoirs has often resulted in complex fracture network growth, as evidenced by microseismic monitoring. The nature and degree of fracture complexity must be clearly understood to optimize stimulation design and completion strategy. Unfortunately...

In this paper we have used a complex fracture network model, which we refer to as the Unconventional Fracture Model (UFM), to study zipper fracturing. The model...
