At least 50 m (164 ft) of an underwater pipeline bringing Russian gas to Germany is thought to have been destroyed by a blast last month.
Europe is investigating what caused three pipelines in the Nord Stream network to burst in an act of suspected sabotage near Swedish and Danish waters.
As the methane emissions subside, the blasts have redrawn the global gas trading map, according to climate data company Kayrros.
Gas is likely to stop leaking from the damaged Nord Stream 1 Baltic undersea pipeline on Monday, the pipeline's operator told Reuters.
A new leak has been discovered on the Nord Stream 1 and 2 gas pipelines in the Baltic Sea, bringing the total number of ruptures to four.
Any deliberate disruption to the EU's energy infrastructure would meet a "robust and united response".
Leaks on Nord Stream pipelines are forming area of natural gas bubbles 1 km in diameter in the Baltic Sea.
Russia’s Nord Stream pipelines are leaking into the Baltic Sea, according to Sweden’s Maritime Authority.
