Appraising Carbon Geological‐Storage Potential in Saline Aquifers Using Two‐Phase Rate‐Transient Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Rate transient analysis (RTA) is a practical and cost‐effective method for CO2 injection data analysis and storage capacity evaluation of saline aquifers. However, the nonlinear behavior introduced by two‐phase CO2–brine flow, coupled with pressure‐dependent fluid and rock properties, significantly limits the applicability of conventional ...
