  1. Compositional modeling of gas injection in tight oil reservoirs

    … increase. Based on various field pilots, gas injection is by far the most promising IOR/EOR technology for tight oil reservoirs. This work developed an improved compositional model and its associated simulator to understand the complex multiphase and multicomponent behaviors during gas

  2. Quantitative monitoring of gas injection, exsolution and dissolution using 4D seismic

    The main concern in the monitoring of gas injection, exsolution and dissolution is the exact spatial distribution of the gas volumes in the subsurface. In principle, this concern is addressed by the use of 4D seismic data. However, it is recognised that the seismic response still largely provides a …

  4. Multiphase mechanisms and fluid dynamics in gas injection enhanced oil recovery processes

    Currently, the Water-Alternating-Gas (WAG) process is the most widely practiced horizontal mode gas injection process in the industry. Although this process is conceptually sound, it has resulted in low (5 – 10%) oil field recoveries. Conversely, the gravity stable mode of gas injection has carved …
