SPE Live Podcast: Understanding Legacy Well Risks in CCS Projects
Description
Legacy wells represent one of the most persistent uncertainties in assessing long-term CO₂ storage integrity. This SPE Live brings together regulatory and scientific viewpoints to explore how the risks posed by old wells can be identified, assessed, and managed. The discussion will examine how regulators approach balance assurance and oversight, while also drawing on field observations and scientific advances that reveal how leakage may manifest, migrate, and be naturally attenuated in the subsurface environment. Together, these perspectives highlight the importance of integrating evidence-based science, effective regulation, and collaboration to build confidence in large-scale CCS deployment.
Attendees will gain insights into the regulatory and assurance aspects of legacy wells, but also explore environmental “fingerprint” of leakage, its detectability, and how science-based diagnostics can support regulatory oversight. Don’t miss this opportunity to engage with experts and enhance your understanding of CCS integrity and risk management.
