Emmanuel Ibe Kachikwu, Nigeria's oil minister said Thursday that the country's oil production, excluding condensates, was slightly below 1.8 million barrels per day in July.
Kachikwu, speaking on the sidelines of an event in the capital, Abuja, said there had been issues with aging pipelines, according to report by Reuters.
In his words, "we continue to have challenges, some of our pipelines are old, so these are basically technical. They are not militancy-induced stoppages, but they are basically maintenance-induced."
Nigeria's oil output has rebounded this year, aided by government efforts to placate militants in the Niger Delta region where the bulk of the country's crude is produced, but it has struggled to maintain peak output levels.
Crude production in the country was cut by more than a third last year when militants carried out a series of attacks on energy facilities in the southern Niger Delta oil hub.
