Nigeria’s top petroleum official has called on investors to help revive the long-stalled Brass and Olakola liquefied natural gas projects, suggesting they could be part of a second wave of gas schemes beyond the 20 developments currently under consideration by the government.

The 10 million tonnes per annum Brass LNG project in Bayelsa State went into hibernation about 10 years ago before construction work began, while the Chevron-led 22 million tpa Olakola scheme — also known as OK LNG — in Ondo State also drifted out of the headlines at about the same time.
