Abstract

Summary

This research evaluates how Downhole Water Sink (DWS) technology and the Huff and Puff (HnP) injection method can be used together for efficient CO2 storage in the main pay reservoir in South Rumaila oil field. The main pay is clastic reservoir surrounded with distinct strength-infinite active aquifer from the east and west flanks. A detailed 3D compositional reservoir flow simulation was used to illustrate that adding DWS improves gas injectivity by lowering the reservoir pressure and making trapping work better. The volumetric assessment proves that the reservoir can hold large amounts of CO, which makes deployment more flexible. The efficient and safe CO2 storage performance was achieved by obtaining a Total Trapping Index (TTI) of 0.99 and a Leakage Index (LI) of 0.002. The integration of DWS and HnP techniques were effectively combined to ensure maximum trapping rate with minimum leakage. Additionally, adopting this workflow on a complicated reservoir in South Rumaila shows that the method is flexible and could be used again in many other reservoirs. This research highlights the significance of novel sequestration methods for attaining global climate objectives, providing a standard for future advancements in carbon capture and storage technology.
