Russian independent Novatek's focus on developing feedstock gas fields for its Yamal liquefied natural gas project in the Arctic has caused its overall gas production volumes to decline.
Novatek saw its gas output in the first half of 2017 drop by 8% to 31 billion cubic metres against the same period of 2016.
According to industry analysts, Novatek is concentrating its efforts on bringing online its Yamal LNG project which aims to ship its first cargo later this year.
