Israel's Delek Drilling said on Wednesday it will pay an average interest of 6.28 percent in a $2.25 billion international bond offering to help it finance development of the Leviathan natural gas project off Israel's Mediterranean coast.

Following a road show, Delek said demand in the bond issue -- divided into four series expected to mature in 2023, 2025, 2027 and 2030 -- reached $7 billion, with over 90 per cent of the amount raised coming from international investors.

The offering, it said, was the largest in the infrastructures sector in the global market since the outbreak of COVID-19, and one of the largest in 2020.

Trade in the bonds on international markets and on the Israeli TACT-Institutional will begin over the next few days.

Delek Drilling, controlled by conglomerate Delek Group , has said that after the offering it would buy back up to $50 million of its existing bonds, including those used to finance the smaller Tamar gas project.

Israel's $3.6 billion Leviathan field - co-owned by Delek, Texas-based Noble Energy and Ratio Oil - started production in late 2019 and is already supplying gas to Israel, Egypt and Jordan.

Last month, Chevron Corp said it would buy Noble for $5 billion in stock.
