The National Infrastructures Ministry
on Sunday ordered a halt to drilling in the Leviathan structure, after water entered the borehole of the Leviathan 2 well, which aims to verify the presence of natural gas in the structure.
"We were very lucky that water, not gas, or God forbid, oil, penetrated the borehole, which could have caused a major ecological disaster," a ministry source told Globes.
No drilling was underway at Leviathan.
Drilling of the Leviathan 2 well was due to resume this week.
