The EU is trying to replace Russian gas with gas from Nigeria, amid the Ukraine-Russia war.
Reuters news agency was told that the Deputy Director General of the European Commission’s energy department, Matthew Baldwin, was in Nigeria over the weekend holding talks with officials.
He was told that the West African nation was strengthening security in the Niger Delta region, where gas is produced.
Officials also told him the Trans Niger pipeline was being reopened, which would increase gas exports to Europe.
Currently the EU gets just 14% of its liquefied natural gas from Nigeria, however, there is scope to double this amount Mr Baldwin told Reuters.
Western leaders have imposed a series of sanctions on Russian oil and gas following the invasion of Ukraine.
The EU has also committed to reducing gas imports from Russia by two-thirds within a year.
