Bahrain has discovered its largest oil field since the country’s first oil well began operation nearly 90 years ago, the AP reported on April 1. The Persian Gulf island nation says the tight oil and deep natural gas field was discovered off the west coast of the island in the Khaleej Al Bahrain Basin.

Bahrain, which is not a member of the Organization of Petroleum Exporting Countries (OPEC), extracts oil from an offshore field it shares with Saudi Arabia and the onshore Bahrain field.

Member of the Representatives Council and Deputy Speaker of the Arab Parliament Adel Al Asoumi extended congratulations to Bahrain’s King Hamad bin Isa Al Khalifa, noting that royal directives contribute to fast-tracking development in various fields, BNA reported. He pointed out that the newly discovered field of tight oil and gas would further contribute to backing the kingdom’s economic security.
