Ratio Petroleum is a partnership with energy business orientation which was founded in 2011. The Partnership was established after the discovery of Leviathan, when the geologist and entrepreneur, Eitan Aizenberg, who has served as the SVP Exploration and Production of Ratio Petroleum since its founding, approached the Landau and Rotlevy families to establish a partnership which would engage in gas and oil exploration worldwide.

Ratio Petroleum’s strategy focuses on operating in areas where great potential is spotted and no significant petroleum discoveries have yet been made, like the Levant Basin prior to the Leviathan and Tamar discoveries. This strategy was proven in the Guyana  Basin, which is currently considered one of the “hottest” locations in the world for exploration, development, and production of oil. From 2015 to this day, over twenty discoveries have been made in the basin, which are estimated at more than 10 billion barrels recoverable oil.

At the beginning of 2021, the Partnership announced the Tanager-1 discovery in the Kaieteur Block offshore Guyana, with proven reserves of approx. 65 million barrels of oil.

Ratio Petroleum currently holds petroleum interests in three different basins on opposite sides of the world: Guyana, Morocco Atlantic, and the East Palawan Basin in the Philippines. The total area of Ratio Petroleum’s petroleum interests is approx. 130,000 sq km. The Partnership continues to search for more assets and investment opportunities around the world.

The partners of Ratio Petroleum are some of the world’s leading energy companies, including ExxonMobil, Hess, ONHYM.

The Partnership made an IPO in 2017, and it is traded on the leading indices of the Tel Aviv Stock Exchange, including the Oil & Gas Exploration Index.



In recent years, Guyana has become one of the most prominent oil and gas exploration and production location in the world, and it is defined as part of the prolific Guyana-Suriname Basin. As part of the accelerated activity in recent years, oil fields were discovered in Guyana with volumes of more than 10 billion barrels of recoverable oil were discovered. Ratio Petroleum holds 25% of a license in the Kaieteur Block, which extends over an area of approx. 13,535 sq km.


In 2016, after winning an international tender, Ratio Petroleum was awarded an extensive exploration area east of the Palawan Island, called SC76. The Partnership, which is also the operator of the block, currently holds 100% of interests of the block, which extends over an area of approx. 6,480 sq km in water depths ranging between 900-1,700 meters.


In 2021, after signing an agreement with the Government of Morocco, Ratio Petroleum was awarded an extensive area for study and research called Dakhla Atlantique, in the Atlantic Ocean. The Partnership currently holds 100% of the block area, which extends over an area of approx. 109,000 sq km in water depths ranging between 0 and more than 3,000 meters.
