..., they may also provide pathways for water to flow into a well during production and may lead to loss of wellbore fluid while drilling. Understanding the spatial distribution and orientation of natural fracture networks is, thus, important in optimizing drilling and production. Fortunately, open or partially...

... an explosive computational effort to account of fractures in standard DC resistivity modeling. Here, we use the hierarchical finite element method (-FEM) to model complex fracture networks in 3D conducting media. The -FEM method is based on the hierarchy in the electrical properties of 3D geologic media...

... ABSTRACT We apply two different approaches to determine the effective connected fracture network, responsible to the Primary production zone, in two shale reservoirs in different basins, generated by hydraulic fracturing stimulation. The first method is a 3D topological approach that uses...

... the borehole, and a fracture network extending from the borehole. Both models contain small fractures surrounding the borehole. Our result shows that wave propagation in the main-fracture model is characterized by significant shear-wave anisotropy for polarization along and normal to the fracture orientation...

..., Canada. In such reservoirs, understanding the spatial distribution of natural fracture networks is key to optimizing production. Fortunately, the presence of fractures can be inferred from variations in reflection amplitude as a function of azimuth and incidence angle. This paper presents the application...

... ABSTRACT This paper describes an advanced methodology for fault and fracture detection using seismic data. The understanding of the fracture network is often necessary for both exploration or production context, as it can be a key driver controlling the fluid movements. In case of highly...

... ABSTRACT The Niobrara unconventional play is one of the main reservoirs in the Denver Basin where well performance depends on the size and efficiency of the interconnected fracture “plumbing system” developed during multistage hydraulic fracturing. A complex natural fracture network can...

Image logs collected along approximately 7400’ of lateral provide additional insights into the fracture network within the Marcellus target zone. Over 1600 fractures were interpreted by the Schlumberger analyst...

... design has now turned its focus to perforating for reservoir rock stimulation. Enhanced fracture network complexity through induced fractures greatly increases the contact area and reservoir drainage for maximum productivity. However, to accomplish the stimulation of both primary and secondary fracture...

... reservoirs is known to generate seismicity due to the interaction of injected fluids with the pre-existing fracture network. Typically, the observed moment magnitudes (M w ) for such operations are small, usually with M w < 0. To map the seismicity during these injections, geophones (utilizing 15 Hz...

... Summary Laboratory wavefront imaging experiments were performed on isotropic samples containing orthogonal fractures to determine the effect of fracture networks on elastic wave propagation. The arriving acoustic wavefront was recorded over a two-dimensional area as a function of time while...
