The effectiveness of carbon capture, utilization, and storage (CCUS) operations relies on precise in‑situ rock and stress characterization for secure and efficient CO2 storage. Identifying, characterizing, and selecting suitable sites for CO2 geological storage necessitates comprehensive evaluation techniques to determine optimal locations for safe and long-term carbon containment. By integrating petrophysics, geology, geomechanics, and reservoir engineering, precise in-situ stress measurements were acquired for two of the operator’s wells, successfully characterizing caprock integrity and reservoir injectivity and creating a blueprint for future CCUS evaluations.
Background
The operator has drilled and evaluated two separate CCUS wells as part of the UAE’s strategic aim of having net-zero emissions by 2050. These wells seek to describe the in-situ geomechanical, petrophysical, and hydrodynamic features of potential storage deposits. In this study, the stress behavior and sealing efficiency of target formations were assessed through downhole testing integrated with formation pressure and fluid sampling.
