Many large oil and gas fields in the most productive world regions happen to be fractured. The exploration and development of these reservoirs is a true challenge for many operators. These difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. To successfully address these challenges, it is paramount to im...

the development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. in petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. in this study, which is a...

iran's proved natural gas reserves are the world's second largest reserves. mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. one of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in produc...

The Upper Triassic Chang-7 Member of the Ordos Basin contains typical tight sandstone reservoirs. Reservoir quality is affected by diagenesis, which a critical factor in oil exploration. In this study, sandstones were studied variety experimental methods, including thin sections, scanning electron microscopy (SEM), and X-ray diffraction (XRD), to determine reservoir characteristics diagenesis d...

Compared with oil, natural gas has been the focus of energy industry in recent years. Renewable is goal and trend future developments, it made considerable progress; however, not reached ideal popularization rate. Therefore, still very important so far. In this paper, influence thermal injection room temperature on reservoir recovery analyzed, method water plugging by hot tight put forward. Ind...

The driving forces behind gas flow and migration, as well the associated gas–water distribution patterns in tight reservoirs, are not only closely related to formation mechanisms of “sweet spots”, but also serve crucial geological foundations for development efficient modes optimal placement. In this work, three methods, namely, critical column height driven by buoyancy, pore throat radius atti...
