CO2 Storage Efficiency
Ensure your investment for the most appropriate storage efficiencies for sustainability.

 

In her paper, Utilizing Multiphase Flow Modeling to Estimate CO2 Solution Storage Efficiency and Sequestration Project Size, author Kacey Garber discusses how developing an understanding of CO2 storage efficiency and CO2 capacity estimates for a Carbon Capture and Storage (CCS) project will help you properly scope your project location and therefore maximize the benefits CCS has to offer.

The storage component of a CCS project requires a Class VI Underground Injection Control permit to inject supercritical CO2. These permits require multiphase flow modeling to delineate both the extent of the injected supercritical CO2 and areas that exceed a critical pressure threshold as a result of injection. SCS has found this modeling to also be valuable during project scoping to provide a sense of the total CO2 storage capacity for a given project.

Kacey walks through a case study that utilized a multiphase flow model to investigate what operational parameters would lead to the most efficient use of pore space for a CCS project in development. This included examining the effects of different injection rates, durations, and locations and investigating multi-injection well scenarios. This case study ultimately shows that a multiphase flow model will help you meet the requirements for your Class VI injection well permit application; it will also help you right-size your CCS project during the planning phase. Incorporating project-specific considerations into the model will help you identify operational conditions ideal for maximizing CO2 storage efficiency.
