Abstract Multi-gas assisted steam huff and puff process is a relatively new thermal recovery technology for offshore heavy oil reservoirs. Some blocks of Bohai oilfield have implemented multi-gas process. However, the development mechanism still requires further study. In this paper, high-temperature high-pressure (HTHP) PVT experiments different sand pack were carried out to reveal enhanced pr...

Surfactants could react with adsorbates on carbonate rock surface to alter wettability from oil-wetness water-wetness, which is effective enhance oil recovery. Surfactant huff-puff treatment mostly applied for this purpose and the resulting surfactant performance outcome of complex interfacial processes. Currently, effect important parameters not completely reported contribution each parameter ...

Heat extraction from deep, hot rocks for energy production is based on water circulation through a man made fracture or natural fractures. As multiple and non-planar fractures in a stress field affect the geothermal reservoir behavior, so the capability to simulate multiple fractures and joints is needed to help reservoir design and operation. A 3D model is developed in this work to simulate an...
