Failure Analysis–Informed Risk Assessment Framework for Geological Carbon Storage Using Numerical Simulation and Machine Learning

H. Wang, Hailun Ni, Tao Bai, Ting Xiao et autres

Summary Geological carbon storage (GCS) is recognized as a critical technology for achieving large-scale reductions in anthropogenic carbon dioxide (CO2) emissions. Ensuring long-term containment and safety requires robust risk assessment frameworks that account for geological uncertainty and identify potential failure scenarios. Among …

Near-Surface Monitoring of Plugged and Abandoned Wells for Real-Time Leakage Detection in Geologic Carbon Storage

Sahar Bakhshian, Hassan Dashtian, Arya Chavoshi, Mahdi Haddad et autres

The risk of CO 2 and brine leakage to environmental receptors is one of the main concerns in geologic CO 2 storage. Legacy wells from past oil and gas activities may be located within the area of review, necessitating continuous monitoring to …

Laboratory Sand Tank Modeling of the Brumbys Fault CO 2 Controlled Release Field Experiment

Hailun Ni, Andrew Feitz, Eric Tenthorey, Hadi Nourollah et autres

Abstract Faults present potential leakage risks for geological CO 2 storage. To de‐risk a field test injecting CO 2 into a shallow fault, laboratory sand tank fluid flow experiments were conducted prior to field injection. The vertical 2.5D sand tank analog models …

Pressure Space: The Key Subsurface Commodity for CCS

Alexander P. Bump, Susan Hovorka

Subsurface injection of CO2 into saline aquifers requires displacement of native reservoir brines at rates similar to that of injection. Common practice assumes that most injection sites behave as though they have open boundaries, such that capacity for brine displacement is effectively …
