A major concern in development of fractured reservoirs in Enhanced Geothermal Systems (EGS) is to achieve and maintain adequate injectivity, while avoiding short-circuiting flow paths. The injection performance and flow paths are dominated by fracture rock permeability. The evolution of fracture permeability can be made by change in temperature or pressure induced rock deformation and geochemic...
Tracer testing in fractured reservoirs has long been limited by the availability of unique and unambiguous tracers. In this study, we introduce the concept of using thermophilic microorganisms and DNA barcoding techniques for fractured reservoir characterization. On the one hand, thermophilic microorganisms have the potential of thriving in the extreme environment of geothermal and oil reservoi...
Seismic curvature gradient is a useful third-order geometric attribute that has demonstrated its value for subsurface structure analysis, especially fracture detection in fractured reservoirs. However, most recent efforts have been primarily focused on predicting fracture intensity by this attribute; and little has been published on applying it to predict most likely fracture orientation, which...
Permeability variation in tight channel sand formation makes an important role in gas production. Based on the features of channel sand formation, a mathematical model has been established considering anisotropy of permeability. The analytical solutions were derived for productivity of both vertical wells and vertically fractured wells. Simulation results show that, gas production rate of aniso...
the main purpose of this investigation is to study the effect of near miscible co2 injection in different porous mediums on both lab and field scales. this effect can be traced by the change of two-phase gas-oil relative permeability curves. in this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...
