Résumé. The two test cases presented herein aimed at simulating the transport migration of nuclides around a nuclear waste repository and belong to the "Two-Phases Numerical Test Data Base" presented in [1], [2]. They were initially designed in the framework of the French research group MoMaS [3]. The starting point in designing all the test cases presented in [1] comes from some of the main ch...

In a typical ultra-deep high-temperature and high-pressure heterogeneous reservoir in Xinjiang, gas channeling quickly occurs during injection because of the heterogeneity reservoir, low viscosity injection, high gas-oil fluidity ratio. The identification prediction methods development were studied. First, discrimination parameters determined by numerical simulation method. According to ratio o...

In this work the likelihood of asphaltene deposition problems during dynamic displacement of oil by natural gas in unconsolidated porous media is experimentally inspected. The two different rock materials, limestone and sandstone, are used as a representative of porous media. Dynamic flow experiments indicate that the increase of natural gas injection increases asphaltene deposition in the unco...

Abstract Enhancing oil recovery in reservoirs with light and high gas content relies on optimizing the miscible water alternating (WAG) injection profile. However, this can be costly time-consuming due to computationally demanding compositional simulation models numerous other well control variables. This study introduces WAG eq , a novel approach that expedites convergence of optimization algo...

Abstract Carbon dioxide (CO 2 ) injection is implemented into the reservoir to further improve oil production efficiency, by mixing with at condition, and becomes miscible. The miscibility affects become swelled less viscous thus easily flow through reservoir. Most of EOR projects has higher recovery factor in miscible condition. Therefore, this article aims determine effects on Cornea Field. F...
