'Shell documents expose ‘basket’ pipeline, ‘missing’ wells and US$10.9bn decommissioning costs as pollution scandal grows’ 29 July 2026

Shell must answer for decades of pollution in the Niger Delta after internal company documents revealed broken rules, failing infrastructure and unresolved clean-up costs that risk leaving affected communities to pay the price, a coalition of human rights and environmental organisations, including Amnesty International, said today in a new report. The report, Nigeria: Lifting the Lid, analyses internal Shell emails, audits, presentations and confidential reviews disclosed in UK legal proceedings, revealing a wider human rights scandal than previously reported. While Shell presented its operations as meeting global standards, the documents point to concerns raised by the Nigerian army over alleged complicity in oil theft, suspected staff and contractor collusion, exemptions from safety standards, chronic neglect of known pipeline integrity risks, missing well data, weak leak detection and flawed spill monitoring.

Shell knew the risks from ageing and leaking infrastructure, including an old pipeline internally described as “a basket” [case], yet kept oil flowing. It later decided to divest its onshore business rather than face the enormous cost of clean-up and decommissioning, including an internal US$10.9 billion decommissioning estimate. A separate internal presentation stated that 375km² of mangrove forest had been harmed by pollution. Amnesty International wrote to Shell on 3 July 2026 to share its findings related to the disclosed documents. In response to Amnesty’s report, Shell wrote that: “The characterisation and portrayal of Shell in your letter is not one we recognise. Shell is committed to honesty, integrity and respect for people, and to conducting business in an ethical and transparent manner.” Shell says that the findings do not reflect the “challenging operating environment in the Niger Delta at the time”. Their full response is included in the report. “Shell has long blamed oil theft and sabotage for pollution in the Niger Delta. But these documents cut through years of denial and raise grave questions about what Shell knew, what it allowed to continue, and whether it then sought to walk away from the costs of its toxic legacy,” said Isa Sanusi, Director of Amnesty International Nigeria.

…The report also reveals that Shell exempted its Nigerian subsidiary, Shell Petroleum Development Company (SPDC) from key elements of its global health and safety standards so oil could continue flowing through tampered pipelines, even when not deemed safe under Shell’s own safety rules. This was an approach one senior Shell executive appeared to acknowledge would not be tolerated elsewhere. Internal documents additionally show Shell executives suspected staff and contractors may have been involved in oil theft, with one email warning: “we have to work on the assumption that the bunkerers get good access to SPDC planning data.” Internal audits further exposed serious weaknesses in Shell’s pipeline management, including a major maintenance backlog, weak oversight systems, and poor records on pipeline clamps that Shell had allowed to become permanent repairs on leaking pipelines. More than 1,600 clamps were registered, including older clamps whose locations were unknown.
