Oil fell more than $2 towards $34 a barrel on Monday after Russia and Ukraine signed a 10-year gas deal clearing the way for the resumption of supplies to a freezing Europe.

Implementation of a ceasefire between Israel and Hamas in Gaza also eased supply concerns as the market remained under pressure from expectations that the weakening global economy would erode oil demand.

“Right now the economy is dominating,” said Harry Tchilinguirian, analyst at BNP Paribas. “The market is very volatile and the signs are that demand is weakening.”

U.S. crude oil futures for February delivery dipped to a low of $33.89, down $2.62, before recovering to trade at $34.53 by 1800 GMT.

Traders said the February U.S. crude oil futures contract, which expires on Tuesday, also fell because of very high stocks at the delivery point for the U.S. futures contract.

Only just over 3,100 lots were traded on the February U.S. crude contract. The March contract was much more active as more than 31,000 lots changed hands.

London Brent crude for March fell to a low of $43.80, down $2.77, before edging back up to around $44.50.

GAS FLOWS

The agreement between Russia and Ukraine, which set a final price for 2009 supplies, is expected to lead to the restart of flows of Russian natural gas to Europe via Ukraine within the next 36 hours.

Also easing concern about energy supplies, Israeli forces began to pull out of the Gaza Strip following a tentative truce with Hamas after the three-week war, easing tension in a region which pumps about a third of the world’s oil.

Prices came under pressure on Friday after the International Energy Agency, an adviser to industrialised countries, predicted a fall in world oil demand in 2009.

OPEC, the oil exporters’ group, has cut production three times since September to try to stem falling prices. It might consider reducing output again, Algeria’s oil minister Chakib Khelil said on Saturday.

Oil has collapsed by more than $110 a barrel since reaching a record high of $147.27 a barrel in the summer as the global economic slowdown has eroded demand and consumer spending.

Still, some in the oil market think there is little room for prices to fall much further.

“It looks as if Brent will hold in the current $40-$50 range,” said Christopher Bellew, a broker at Bache Commodities. “I do not anticipate new lows.”

LONDON, Jan 19 (Reuters)

Global consumption is growing almost twice as fast as for oil, it is the cleanest-burning of the fossil fuels, and it is comparatively cheap: it currently trades at about half the cost of crude oil on an energy-equivalent basis.

In an energy-hungry world, it’s therefore not surprising that there’s now a mad scramble to procure long-term supplies and bring them to market.

Let’s take a look at some of the current major developments…

Pipelines. Russia, which has the world’s biggest reserves of natural gas, is building a direct link to Germany beneath the Baltic Sea, and planning others to China and Italy. These are enormous undertakings. The 3,000km Italian link, for example, is expected to cost $15bn.

Elsewhere, the ConocoPhillips-BP pipeline to bring North Slope gas from Alaska to Canada’s oil sands industry and the lower 48 US states will be the largest private-sector construction project in North America. And the pipeline China is building from Turkmenistan in Central Asia to Shanghai will stretch for 9,000 kms.

Liquefaction. An alternative means of moving gas is to liquefy it by freezing, ship the liquids across oceans, then turn it back into gas. The technology is not new, but LNG (Liquified Natural Gas) facilities are hugely expensive. For years this limited its transportation to countries not accessible by pipeline, mainly Japan.

But high energy prices have now made LNG viable on a large scale. And there are other advantages. European nations, for example, nervous about their increasing dependence on Russian gas, are looking to alternative sources such as North Africa, using LNG. China signed a $60bn deal with Qatar last month to buy three million tons of LNG a year over 25 years from 2011.

With its volumes growing 7% a year, LNG is the fastest growing of the fossil-fuel industries. Because of the massive investments required, it is dominated by a handful of very large multinationals.

New Reserves. Oil majors are boosting efforts to find and tap hydrocarbon deposits that are primarily gas, with oil as a side-product.

The newly-discovered Sugar Loaf field under the Atlantic off Brazil, claimed to be one of the world’s biggest, is primarily a natural gas resource. The Shtokman development in the Barents Sea off Russia’s Arctic coast, and several projects off the coast of north-west Australia, focus on production of gas, not oil.

There is also increasing interest in exploiting hard-rock resources that have been neglected in the past because it’s difficult to tap their gas. On the western slopes of the US Rockies, Exxon Mobil is starting to employ an explosive fracturing technique three times more effective than conventional technology to unlock the riches of the Piceance Basin.

Coal-bed Methane. The “fire-damp” found in coal deposits – the curse of miners throughout the ages – is almost pure methane and an excellent substitute for natural gas, which is about three-quarters methane. It may be recovered from worked-out collieries or from coal deposits left unexploited because they are so gassy they are too dangerous to mine, and already accounts for a tenth of natural gas production in the US.

BG Group, the global specialist in the discovery, extraction and supply of natural gas, plans to build the world’s first plant to produce LNG from coal-bed methane piped 400km from fields in the interior of Queensland, Australia.

Liquid fuels. Although currently used as gas to fuel central heating, industrial furnaces and power stations, natural gas can be converted into liquid fuels. In Qatar, which has the world’s third largest gas reserves, they’re building plants to do just that.

Worldwide demand for natural gas has been growing at an average rate of nearly 3% a year, compared to oil’s 1.7%. China’s gas consumption is forecast to triple over the next 12 years, India’s to double. Yet between them they have less than 2% of global reserves, so they will be forced to look to imports from the Mideast, Russia and Australia.

Investing in natural gas: major role in power stations

The strongest demand growth area for natural gas is in electricity generation. Dirk Beeusaert, chief executive of Suez, the world’s biggest operator in the field, says the investment cost per kilowatt of power from gas turbines is “half that of a coal plant, and a third of that from a nuclear plant of the same capacity.”

Gas power stations can be built quickly, are flexible in operation, reduce dependence on other resources such as coal, oil and nuclear – and have particular attractions in these times of ecomania. Not only do they produce less greenhouse gases than other fossil fuel, but they can be used efficiently to generate intermittent power, to fill the gaps when turbines driven by wind and water shut down because of calms or droughts.

A couple of decades ago, gas accounted for little of the world’s electricity generation; now it fuels almost one-fifth.

Although the oil majors are giving increasing attention to finding and producing natural gas, most of the world’s resources are closed to them, or are politically high-risk. Russia seeks to use its gas supplies as a strategic weapon in its dealings with Europe and is squeezing out foreign companies. Iran is a different kind of political minefield. Qatar is happy to partner international oil firms, but is also right in the middle of the potentially explosive Middle East.

One country that is benefiting from all this is Australia, which has reserves almost as large as those of the US, production that is likely to continue expanding for the next quarter-century, and a business-friendly environment. Chevron’s Gorgon project alone, which got its go-ahead from regulators a few months ago, expects to produce more than a trillion cubic metres of gas over its 60-year life.
