RERI is a nonprofit research and educational organization which was founded in January 1990 to carry out in-depth research in some key areas of petroleum reservoir engineering. The institute has evolved as a world leader in the areas of thermodynamics of hydrocarbon reservoirs and production, gas injection processes, and fractured and layered reservoirs. Experimental, theoretical, and numerical research are conducted at RERI. Laboratory research work is performed at our laboratory equipped with high pressure visual coreholder and flooding apparatus which can house several large-size matrix blocks. The research projects are divided into two main categories: Thermodynamics Fluid Flow
