Different sensors, from extensometers and inclinometers to fiber optics and deformation gauges, will be installed. A multi-physical assessment of the fracture network around the intersection will lead to its...

... Abstract The present study investigates the use of energetic stimulation for the purpose of creating fracture networks for inter-well communication. Explosive loading is applied in scaled wellbores within a polymethylmethacrylate (PMMA) sample. Prior to testing, the experiments...

... ABSTRACT: A fully coupled thermal-hydraulic-mechanical (THM) model was developed to investigate the heat extraction process of an artificial enhanced geothermal system (EGS). The random fracture network in the stimulated geothermal reservoir was generated by the fractal theory. The local...

... was limited. Increasing the injection rate to 20 mL/min is helpful for HF initiation and propagation. Intense AE activity was simultaneously monitored. Three-dimensionally distributed AE events indicated the generation of complex fracture network. Consequently, the SRV significantly increased from 624 to 3126...

... and closure behavior of natural fractures, respectively. The effect of some initial field conditions such as in situ stress and initial opening of the NF – on the hydraulic fracture propagation has been studied. A fracture network of a real reservoir is also studied, assuming open and sealed natural fracture...

... ABSTRACT: Hydraulic fracturing technology is the key method to reconstruct unconventional oil and gas reservoir. Many results getting from the micro-seismic monitoring show that in shale reservoirs, hydraulic fractures and the natural fractures construct a complicate fracture network...

... fractures in the formation. Numerical models that have been used to capture the complexity of these created fractures require discretized fracture networks (DFN) as an input. Such models rely on the input DFN as a characterization of the reservoir heterogeneity. In this work we show that it is possible...

These unconventional reservoirs are often characterized as anisotropic, highly laminated, and very low permeability, and contain a varying degree of natural fracture networks (NFNs). Therefore, different techniques are used to unlock these massive reserves, including...
