Long-Berenger Oil Agreement (April 1919) was an agreement between France and the United Kingdom over oil rights. This agreement delimited the oil interests in Russia and Romania, British (British Mandate of Mesopotamia) and French colonies. France received a 25% share in oil interests. The agreement takes the names of the British petroleum minister, Sir Walter Long, and the French petroleum minister, Henri Bérenger, who negotiated the agreement.
The Agreement became the basis for the San Remo Oil Agreement of 1920, which gave France a 25% share of Iraqi oil.
