News of the likely new gas find, initially reported by lapoliticaonline, followed reports that exploration by Repsol-YPF had concentrated on the Patagonian province of

Neuquen.

Argentine President Cristina Fernandez de Kirchner is expected to make a formal announcement of the discovery this week, MercoPress reported.

Estimates about the size of the find suggested that, once developed, the gas deposits could likely make Argentina self-sufficient in energy for at least half a century.

Neuquen already is known for its hydrocarbons, largely undetermined but believed to be the result of extensive fossil deposits.

Argentine oil and gas production has suffered for almost a decade due to low productivity, labor disputes and related problems. An exploration program in both oil and gas sectors suffered several interruptions due to political troubles in both Argentina and Bolivia.

Several of the biggest hydrocarbon companies in South America, including Brazil's state-controlled Petrobras, have been actively looking to increase their investment in Argentina's energy sector.

Exploration experts linked to the operation told Argentine news media they were hopeful the natural gas quantities in Neuquen would be very substantial.

Officials said the latest discovery made them confident Argentina would have ample quantities of fuel for the coming decades.

"Argentina has gas for the next century and we can cut off from Bolivian imports," said Miguel Hassekieff, a senior energy official.

Tentative primary testing for the gas reserves estimated the volume of the deposit could be at least 21 trillion cubic feet.

Meanwhile, Repsol YPF said it resumed operations at southern Argentina's oil fields that were disrupted by an oil workers' strike that began Dec. 1.

YPF is Argentina's largest producer of crude and already the second-biggest producer of natural gas in the country. Officials said full-scale exploitation of new natural gas deposits could take several years to be implemented. In the meantime, Argentina would remain dependent on imported oil and gas.

Fernandez has announced plans to speed through a government plan to expand nuclear power generation with the establishment of a new nuclear power generation plant to add to two already in operation.

The nuclear reactors generate nearly 1-10th of Argentina's electricity. But electricity consumption in Argentina has grown steadily since 1990, giving impetus to the government's efforts to increase and diversify sources of energy.

Desire hopeful of new Falklands oil find
Stanley, Falkland Islands (UPI) Dec 3, 2010 -Desire Petroleum, which has staked shareholder capital on finding commercially viable quantities of oil in the South Atlantic's North Falkland Basin, said its latest drilling held promise of a discovery it could work with.

The company made the announcement after fresh drilling of the so called 14/15-2 Rachel North well reached a new depth of about 10,000 feet.

Desire Petroleum plc, a U.K. company listed on the Alternative Investment Market, was one of the first prospectors to enter the fray but has trailed other companies actively seeking to strike significant oil below the North Falkland Basin seabed.

The oil quest has coincided with an increasingly bitter war of attrition between Argentina and Britain over Argentine claims of sovereignty. Argentina maintains the London-ruled Overseas Territory is a vestige of British colonialism and should go under Argentine rule as Las Malvinas.

Argentine claims on the Falklands culminated in an invasion in 1982 that was repulsed by Britain. The 74-day conflict led to 1,000 deaths of fighters from both sides and some Falklands civilians.

The Argentine claims hardened as the oil prospecting progressed. Last week Argentina won support from Latin American neighbors in what promises to be a campaign to block the Falklands' shipping trade.

British, Falkland and other shareholders have staked millions on a major oil find, which some surveys suggest may turn out to be bigger than the North Sea reserves. Results so far are not encouraging, however, but analysts insist that may change.

A Desire Petroleum announcement struck a note of cautious optimism. A technical update laced with industry jargon said preliminary data indicate that "this well is an oil discovery," the company said.

Desire "has run an initial suite of wireline logs and this together with the drilling data indicate that the well encountered a 349-meter gross interval from 2,621 meters to 2970 meters of sands and shales with hydrocarbons, of which 57 meters is net pay in multiple zones," the company said.

Oil industry analysts and geologists differ when defining oil well net pay, but it usually sums up the quantity of explored mass that can be used to produce commercially viable quantities of oil.

"The thickest zone is 8 meters thick with an average porosity of 20 percent. Other zones are thinly bedded and lower porosity but require further analysis from additional wireline logs to establish reservoir potential," Desire said.

"Desire now intends to complete the wireline logging and wireline sampling program to obtain more information on the reservoir quality, the hydrocarbon saturations and the fluid type to assess the significance of this discovery." It promised to provide more information later.

Desire Chairman Stephen Phipps termed "highly encouraging" news of the initial drilling results from the Rachel North well.

He said the new discovery, combined with Rockhoppers' Sea Lion earlier discovery, confirmed the prospecting firms' belief the North Falkland Basin was "highly prospective and that further oil fields will be discovered in this area."

At least six oil prospecting firms are actively looking for oil and gas in the Falklands waters, much to public fury of Argentine government officials.
