The company's Nigeria division stated that their spill response team managed to contain the overflow and notified the relevant authorities.
They also mentioned that plans are in place for a joint visit led by regulators to investigate the cause and effects of the spill, according to a Shell spokesperson.
The Niger River delta has suffered from decades of oil spills, leading to significant environmental harm that has devastated the livelihoods of countless local residents and affected their health.
The Youths and Environmental Advocacy Centre (YEAC-Nigeria) reported that the spill happened when an underground pit filled with crude oil began leaking into a pipeline linked to the Ogoni cleanup project.
