The agreement struck between the five permanent members of the UN Security Council plus Germany (P5+1) and Iran on March 2 paved the way for a comprehensive deal to begin lifting sanctions in late June. Iran has been off limits to most foreign investors for nearly a decade. Unsurprisingly, it is regarded as El Dorado by many international corporations, particularly those in the energy sector.

Exxon is the world’s largest listed energy group, and like all big international oil companies it is facing structural challenges that make it difficult for it to grow. Stability while throwing off a lot of cash may be the best they can do.

Wintershall will continue investing in its core regions, with Russia remaining the most important area for the company.

Real gross domestic product -- the value of the production of goods and services in the United States, adjusted for price changes -- decreased at an annual rate of 0.7 percent in the first quarter of 2015, according to the "second" estimate released by the Bureau of Economic Analysis.

The US and EU sanctions are primarily targeted at the country's oil industry, for very obvious reasons. Russia provides about 30% of Europe's gas, so it's simply not in the EU's interests to compromise Gazprom's ability to produce and export gas.

Discoveries of natural gas offshore Israel signalled the eastern Mediterranean as a new frontier for the development of natural gas resources. The gas discoveries provide a unique opportunity for Israel to change its mentality vis-à-vis neighbouring countries and view the resources as a tool for strengthening regional cooperation and solidarity through energy diplomacy. While security concerns in Israel remain paramount, diplomacy in the context of the eastern Mediterranean transcends traditional foreign and security policy considerations, and attempts to use economic and commercial means to interlink the countries of the region through energy relations.

Crude oil prices are still about half their value compared with a year ago, but the now prolonged slump is unfolding such that another rise could be on the horizon

Turkmenistan is systematically increasing the volumes of contracts for the gas supply to China. And taking into account the growing demand for gas in China, the gas supplies from Turkmenistan to China will continue to grow.

Millions of barrels of untapped oil that U.S. shale drillers discovered during the boom years are about to disappear from their inventories.

Russian energy company Gazprom has made it clear that it intends to move forward with the construction of the Turkish Stream natural gas pipeline as quickly as possible, whether or not the project can overcome political obstacles in Europe.
