Prospects for a major Russia-Japan joint-venture liquefied natural gas project receiving a final go-ahead have improved as a consequence of Japan's earthquake and nuclear disaster, the head of one of the companies involved said Thursday.

Prospects for a major Russia-Japan joint-venture liquefied natural gas project receiving a final go-ahead have improved as a consequence of Japan's earthquake and nuclear disaster, the head of one of the companies involved said Thursday.

"It will accelerate our LNG project with Russia," Osamu Watanabe, president of oil and gas explorer Japan Petroleum Exploration Co., told Dow Jones Newswires.

Japan is the world's biggest buyer of LNG, and since the March 11 quake, government and company executives have been lining up additional short-term supplies to feed thermal generators, to make up for shortfalls in electricity supplies caused by nuclear reactor damage and closures. They are also working on plans to ensure sufficient gas imports in the decades ahead.

In the financial year that began April 1, Japan's LNG demand will rise by roughly 10 million metric tons because of increased gas-fired electrical generation, the Institute of Energy Economics Japan said in a recent report.

A Japanese consortium including Japex agreed in April with Russian gas firm OAO Gazprom to go ahead on a feasibility study for a 10 million-metric-ton-a-year LNG export project based at Russia's Pacific coast port of Vladivostok, aiming to complete this by end-2011.

"We were in a pre-feasibility-study stage well before the March earthquake. But now, Russia is very enthusiastic. I expect the project will move on faster than previously thought, given that it's easier to make an investment decision thanks to rising energy prices," Watanabe said.

The business environment for fossil fuel upstream developments had benefited from doubts about nuclear energy as spot LNG prices and oil prices had already risen, and now Japanese utilities are rushing to buy to make up for lost nuclear output in Japan, he said.

The rising trend in LNG and oil demand--and prices--is likely to last for years as construction plans for new nuclear power stations have been delayed, Watanabe said.

Tokyo Electric Power Co., the operator of the stricken Fukushima Daiichi nuclear power plant complex, has bought 3 million metric tons of LNG for the use in summer months.

Chubu Electric Power Co. (9502.TO), which shut its Hamaoka nuclear power plant after government requests following the Fukushima disaster, has secured 1.6 million tons, and is working on buying another 1.6 million tons, all to be used this fiscal year ending in March 2012.

Right after the quake, Japanese utilities suspended construction work on four new reactors. Now, roughly half of Japan's 54 reactors are offline, with utilities unable to restart reactors idled for routine maintenance at a time when anti-nuclear protests in Japan are on the rise.

"We are also looking into several LNG project candidates in different areas," the Japex official said.

He didn't specify possible partners or countries, but noted that while previously the global LNG market had been oversupplied, after the March 11 disaster, it's been tightening.

State-owned Qatargas has said that it is ready to meet any increase in Japanese demand for LNG, and Chief Executive Sheikh Khalid Al-Thani said late March that the company foresees a 36% increase in LNG demand by 2025.

Japanese officials have been in Indonesia to try to arrange additional near-term deliveries, and several of the nation's power utilities are in talks on more long term supplies from Australia, which has a raft of LNG projects in the development stage.

Japex, a former state-owned gas and oil producer, used to focus on development of Japan's tiny domestic gas and oil reserves.

But in its new business plan covering the five years started on April 1, Japex said it aims to allocate some 60% of its Y280 billion planned investment in overseas businesses compared with roughly 30% in the previous plan.
