Amnesty reveals internal Shell documents pointing to ageing Niger Delta pipelines, missing wells and $10.9bn decommissioning liability

On 28 July 2026 Amnesty and partner groups published internal Shell documents (2008–2014) showing chronic pipeline integrity failures, missing well records and an internal US$10.9bn decommissioning estimate, and flagged that Shell continued flows through an internally described “basket” pipeline despite known leaks.

Disclosed evidence of ageing, poorly monitored onshore pipelines and missing well records raises the probability of episodic production outages in the Niger Delta. That operational risk can translate into fiscal revenue volatility and FX pressure for Nigeria and increase credit risk premia for sovereign bonds and oil-linked corporate credits if supply disruptions or remediation liabilities materially reduce export receipts or require larger fiscal transfers.
