About Ratio Petroleum


Ratio Petroleum engages in oil & gas exploration, development and production around the world.

Ratio Petroleum started as a joint venture by the Landau and Rotlevy families and geologist Eitan Aizenberg, the father of the Leviathan ~22 TCF gas discovery. For further details related to Leviathan discovery and Ratio Oil Exploration (1992) Limited Partnership see

Following the discovery of Leviathan, Aizenberg, together with his partners the Landau and Rotlevy families, initiated the idea of exploring for oil & gas outside of Israel.

The strategy of Ratio Petroleum was to focus on under-explored basins, where significant oil discoveries had not yet been made, like the Levant Basin prior to the discovery of Leviathan and Tamar natural gas fields.

At present, Ratio Petroleum holds petroleum rights in two different basins around the world in Guyana-Suriname and the Philippines. The area of Ratio Petroleum’s petroleum rights totals -22,330 sq km.

Within a short period of getting underway, Ratio Petroleum’s professional capabilities were proven when near the Kaieteur Block that it holds in Guyana, ExxonMobil, the largest energy company in the world, discovered the giant Liza oil field (up until this discovery, oil had never been produced in Guyana’s Exclusive Economic Zone). Shortly after the Liza discovery, ExxonMobil joined Ratio Petroleum as a partner and as the operator in the Kaieteur Block.

Ratio Petroleum’s securities are traded on the Tel Aviv Stock Exchange (RTPT.L).
