Chan","doi":"10.2118/178439-PA","DOIUrl":"https://doi.org/10.2118/178439-PA","url":null,"abstract":"Summary In this paper, a new hydraulic-fracturing model is introduced for cohesionless sand, which is also applicable to weak sandstone for- mations with high permeability and low shear strength. Phenomena such as shear-band development and shear-enhanced permeability are of paramount importance during hydraulic fracturing of cohesionless sand or weak sandstones, which make the fracturing response quite different from what it is conventionally believed to be in competent rocks. The smeared approach in simulating hydraulic fracturing has been implemented in the proposed model within the continuum mechanics framework. Both matrix and fracture flow have been considered in this model. Tensile- and shear-fracture development and their fluid flow were simulated. The cubic law and Touhidi-Baghi-ni’s shear-permeability model (Touhidi-Baghini 1998) were used to capture the permeability evolution and to model flow in tensile and shear fractures, respectively. Shear fracturing of geomaterials involves intense localization of deformation and strain softening, which is a discontinuous phenomenon, resulting in mesh dependency of the results in the continuum model. The fracture-energy-reg-ularization method was used in this model to reduce the mesh-size dependency of the energy dissipated during fracture propagation. The smeared-fracture approach has been validated against lab- oratory hydraulic-fracturing experiments with reasonable agreement. Consistent with the experiments, the results of the numerical model indicate that tensile fractures are formed in a very small area around the injection point despite the application of high injection pressure compared with the minimum boundary stress. It is found that shear fracturing and shear-permeability evolution are the most important mechanisms that influence and control the fracturing response. The dominant fracturing mechanism is found to be governed by the high permeability and low shear strength of the material.","PeriodicalId":15181,"journal":{"name":"Journal of Canadian Petroleum Technology","volume":"54 1","pages":"460-474"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2118/178439-PA","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67767428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fractures were modelled using the continuum approach in a commercial finitedifference code, labeled the \"softening ubiquitous joints\" model, with randomly distributed strength parameters to describe heterogeneity along the fracture plane. The models allow for intersecting fractures to represent realistic scenarios. The permeability values in the fractures are dynamically updated during the simulations together with the reversible tensile opening because of elastic response and irreversible shear opening caused by plastic deformations. The reactivation of the fracture network resulted in high permeability along these fracture planes. The developed model can predict microseismic events caused by slip on the fracture planes. The magnitude levels of these microseismic events are comparable with the levels observed in events monitored by use of geophone arrays during hydraulic-fracturing treatments for different shale gas reservoirs. © 2015 Society of Petroleum Engineers.","PeriodicalId":15181,"journal":{"name":"Journal of Canadian Petroleum Technology","volume":"54 1","pages":"450-459"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2118/178437-PA","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67767508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intervertebral disk herniation and central degeneration of the disk are two major reasons for low back pain, which occur because of structural impairment of the disk. The reduction of cell count and extracellular matrix, especially in the nucleus pulposus, causes disk degeneration. Different scaffolds have been used for tissue repairing and regeneration of the intervertebral disk in tissue engineering. Various methods are used for fabrication of the porosity scaffolds in tissue engineering. The freeze drying method has disadvantages such as: It is time consuming, needs high energy, and so on. The freeze-gelation method can save a great deal of time and energy, and large-sized porous scaffolds can be fabricated by this method.
