Despite the lack of agreement with Lebanon in the dispute over the future sea border, the Karish gas field in the Mediterranean has already been connected to Israel's national production system.
The British-Greek company Energean announced on Sunday that as part of a test, gas had been transported in the opposite direction, i.e. from the coast towards the platform, for the first time.
It is not yet about the start of gas production, but about testing the systems.
The gas field is part of a dispute over a sea area that both Israel and Lebanon claim as an exclusive economic zone.
The decades-long conflict over the course of the border intensified after the discovery of natural gas resources.
Israel wants to start producing gas from the Karish gas field as soon as possible.
The Lebanese Shiite militia Hizbullah had described the start of funding as a "red line" before an agreement was reached.
Israel shot down several Hezbollah drones on the platform in early July.
Hopes for a quick agreement in the dispute between the warring countries over their sea borders had recently been dashed.
However, according to media reports, the negotiations continue.
On Thursday, Israel rejected Lebanon's proposed amendments to a compromise proposal by the United States.
It is feared that a failure of the negotiations, which have been going on for about two years, could lead to further tensions in the region.
On November 1st there will be parliamentary elections in Israel.
The gas from Israel could also help ease Europe's energy crisis.
Since the Russian invasion of Ukraine, the EU has increasingly been looking for other gas suppliers.
