Bahrain has announced that it has discovered the largest oil and gas field in the kingdom.
State-run BNA news agency said the newfound reserve is many times the volume of Bahrain's only other known oil-field.
No official information about the size and expected date of start of production is yet released.
Bahrain is the smallest producer of hydrocarbons in the Gulf Cooperation Council, which also groups Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates.
Bahrain currently has only one oilfield with several hundred million barrels of crude reserves.
The current capacity of Bahrain's oil field is around 50,000 barrels per day (bpd) and the size of the reserve is over one billion cubic feet (28 million cubic meters). Bahrain receives another 150,000 bpd from the Abu Safa oilfield which it shares with Saudi Arabia.
Around 80 percent of the revenue of Bahrain comes from oil.
