A confidential attachment to a Shell pipelines exception letter dated November 2012 has revealed the scale of illegal connections affecting the company’s pipeline infrastructure in Nigeria’s Niger Delta, highlighting the persistent challenges of crude oil theft, sabotage and environmental damage in the region.
The document, signed by Jurgen Janzen of Shell’s Pipeline Asset Organisation, stated that several pipelines had been classified as “red” under GAIR safety definitions because of illegal taps installed by oil thieves.
According to the document, the presence of even one unauthorised connection is enough to render a pipeline non-compliant with technical standards and in need of immediate corrective action or shutdown.
Shell acknowledged that removing all illegal connections would require significant downtime, but noted that such shutdown periods often create opportunities for new illegal taps to be installed elsewhere on the network.
The document disclosed that in 2012 alone, more than 140 illegal connections were removed from Shell pipelines, while about 90 known illegal connections remained active across the system.
It stated that all known taps were logged with coordinates in the company’s Pipeline Integrity Management System and monitored daily by right-of-way surveillance contractors.
Where leaks occurred, Shell said affected lines were immediately shut down, isolated and depressurised to minimise spills before repairs were carried out.
For non-leaking connections, the company said preventive removal was sometimes undertaken when operational opportunities allowed.
The report also referred to Shell’s Oil Theft DRB initiative, which was aimed at reducing theft volumes and limiting environmental damage caused by illegal connections.
It added that Shell, in partnership with SGS, was exploring alternative methods of disabling non-leaking taps without interrupting pipeline flow, in order to restore pipeline integrity under GAIR standards.
However, the document admitted that leaking clamps would always require production shutdowns for repairs, either through clamping or sectional replacement.
The memo underscores the scale and persistence of oil theft in Nigeria’s pipeline network, where criminal activity continues to drain national revenues while forcing operators into repeated cycles of shutdowns, repairs and renewed sabotage.
Despite surveillance, monitoring and technical interventions, Shell acknowledged that the problem remained systemic, with oil thieves exploiting downtime to establish fresh illegal connections.
The disclosure follows earlier reports on confidential internal Shell emails from October 2008, which revealed disagreements among senior executives over whether to continue operating the Nembe Creek Trunk Line despite concerns that the pipeline was outside technical integrity standards and vulnerable to sabotage.
In the emails, Markus Droll, then Shell’s Technical Vice President, warned that the company was “pretty exposed” by its decision to keep the line running.
He argued that the justification for not shutting down supplying wells was weak and warned that another major explosive attack could force an immediate closure.
Droll also insisted that the installation of Non-Return Valves to protect wells should be treated as a priority alongside pipeline replacement, noting that sabotage could easily recur even after repairs.
Ann Pickard, Shell’s Regional Executive Vice President for Africa at the time, acknowledged the risks but defended the decision to continue operations.
In her email, she described the situation as a choice between two risky options and concluded that the lower risk to people and the environment was to keep operating under the proposed mode.
She agreed to begin purchasing the valves but maintained that continued production was the safer option under the circumstances.
