Last week, Exxon-Mobil won a court ruling against Venezuela's state oil company, PdVSA, over Hugo Chavez's expropriation of oil facilities. Bloomberg's Joe Carroll and Steven Bodzin explain:

Exxon Mobil Corp. won court orders in the U.S., U.K., the Netherlands and the Caribbean freezing more than $12 billion in Venezuelan assets amid a battle over the government's seizure of oil projects.

Exxon Mobil, the world's largest oil company, sought the orders on concern the Venezuelan state oil company will shift assets to other Latin American countries and China to put them out of reach of an international arbitration commission, the company said in a U.K. court filing.

Petroleos de Venezuela SA, the state-owned oil company known as PDVSA, seized joint ventures with foreign energy companies last year as part of President Hugo Chavez's program to bolster government control of Venezuela's resources. Exxon Mobil and ConocoPhillips abandoned the projects rather than accept reduced roles and profits....

Exxon Mobil's lawyers scoured regulatory filings, financial statements and PDVSA directors' reports to dig up bank account numbers, details on U.K. office leases, staffing levels and car fleets to bolster its case, the British ruling showed....

The British injunction was granted Jan. 24 without prior notice to the Venezuelan oil company, according to a copy of the ruling. The next hearing on the matter is scheduled for Feb. 22.

Until then, PDVSA is barred from removing any assets in England or Wales up to a value of $12 billion. The Venezuelan company was also ordered not to sell or diminish the value of any assets within or outside those countries up to the same value.

Among the assets cited were refineries in Scotland and northwest England.

PDVSA probably was already withdrawing assets from England and Wales prior to the freeze order "consistent with PDVSA's approach of withdrawing its business operations from the U.S. and Europe and instead focusing on jurisdictions such as Russia, Belarus, Cuba, China, Syria and Iran,'' Exxon Mobil said in the U.K. filing....

The asset freezes will damage PDVSA's ability to raise funds from international investors for drilling and refinery projects, said Asdrúbal Oliveros, chief economist at Caracas- based Ecoanalitica. He estimated PDVSA has $13 billion in "liquid'' international assets.

"This is going to put a lot of pressure on country risk, and on the price of the company's bonds in the international market,'' Oliveros said. ``Loaning money to a company that's in this kind of dispute, and also is facing this kind of injunction, is going to be very delicate.''

President Hugo Chavez on Sunday threatened to cut off oil sales to the United States if Exxon Mobil Corp. wins court judgments to seize billions of dollars in Venezuelan assets.

"If you end up freezing (Venezuelan assets) and it harms us, we're going to harm you," Chavez said. "Do you know how? We aren't going to send oil to the United States. Take note, Mr. Bush, Mr. Danger."....

"I speak to the U.S. empire, because that's the master: continue and you will see that we won't sent one drop of oil to the empire of the United States," Chavez said during his weekly radio and television program, "Hello, President."...

Chavez has repeatedly threatened to cut off oil shipments to the United States, which is Venezuela's No. 1 client, if Washington tries to oust him. Chavez's warnings on Sunday appeared to extend that threat to attempts by oil companies to challenge his government's nationalization drive in courts internationally.

"If the economic war continues against Venezuela, the price of oil is going to reach $200 (a barrel) and Venezuela will join the economic war," Chavez said. "And more than one country is willing to accompany us in the economic war." (emphasis added)

On the other hand, whatever twinge the U.S. felt would be mild compared to the massive spasms that would rip through Venezuela's economy from such a move -- especially since the only refineries that can handle Venezuelan oil are based in the United States.

Furthermore, it's not like Venezuela's economy is all sweetness and light these days:

These should be the best of times for Venezuela, blessed with the largest conventional oil reserves outside the Middle East and oil prices near record highs. But this country’s economic and social problems have become so acute lately that President Hugo Chávez is facing an unusual onslaught of criticism, even from his own supporters, about his management of the country.

In a rare turnabout, it is Mr. Chávez’s opponents who appear to have the political winds at their backs as they reverse policies of abstention and prepare dozens of candidates for pivotal regional elections. Mr. Chávez, for perhaps the first time since a recall vote in 2004, is increasingly on the defensive as his efforts to advance Venezuela toward socialism are seen as failing to address a growing list of worries like violent crime and shortages of basic foods.

While Mr. Chávez remains Venezuela’s most powerful political figure, his once unquestionable authority is showing signs of erosion. Unthinkable a few months ago, graffiti began appearing here in the capital in January reading, “Diosdado Presidente,” a show of support for a possible presidential bid by Diosdado Cabello, a Chávez supporter and governor of the populous Miranda State.

Outbreaks of dengue fever and Chagas disease have alarmed families living in the heart of this city. Fears of a devaluation of the new currency, called the “strong bolívar,” are fueling capital flight. While the economy may grow 6 percent this year, lifted by high oil prices, production in oil fields controlled by the national oil company, Petróleos de Venezuela, has declined. Inflation soared by 3 percent in January, its highest monthly level in a decade.

I strongly suspect that Chavez's self-preservation motive will force him to back down -- but it would be kind of amusing if he believed his own bluster.
