STEAMFLOOD-Core flood system for EOR by steam injection


Steam flooding has become an increasingly common EOR method for heavy crude reservoirs. A greater recovery is achieved via modifications of quantities such as viscosity, specific gravity, relative permeability and interfacial properties. The Steam Flood performs steam injections into reservoir core samples at reservoir conditions, therefore replicating the steam flooding process. Change in permeability, displacement efficiency, expected oil recovery with various steam flood criteria, are determined from the experiment. The apparatus can be utilized to investigate the effects of temperature rise on viscosity reduction in heavy oil and consequently, the production rate. The core flooding system is equipped with a steam generator to generate superheated steam at temperatures up to 325 °C and pressures up to 2,500 psi. The steam and hot water are injected into a confined core sample whose saturation profile has been restored to that of its reservoir.
