This is a very interesting subject, i use Google to find this information, and it is easy to find:
This shows Chevron, the multinational with so many legal problems in Ecuador, has been welcomed in Venezuela, and is receiving awards of very large oil properties.
"Merida, February 12th, 2010 (Venezuelanalysis.com) – In the largest oil investment decision since Venezuelan president Hugo Chavez was elected, the government announced on Wednesday that private companies from Japan, India, Malaysia, Spain, the United States, and Venezuela, making up two consortiums, won the bid to explore and exploit the Carabobo block of Venezuela’s Orinoco oil belt.
After reminding listeners that before his government, the petroleum industry had been in private hands without benefiting his people Chavez stressed, “We’ve formed joint companies
as the law demands, and PDVSA has majority stocks and control of at least 60% in all these companies...”
The bidding process began on 30 October last year, and PDVSA president Rafael Ramirez said that 21 international companies had participated and offered various amounts for the three blocks of the Carabobo section"

I was curious about this topic discussed in this report from venezuelanalysis, and I found this:
"In October 2008, Venezuela launched the Carabobo bid round, the first held under President Chavez. The round included the extra-heavy oil reserves in the Orinoco Belt that are in the process of certification and specifically focused upon three projects covering seven blocks in the Carabobo area. PdVSA would take a majority stake in each project, which would include integrated upstream and upgrading facilities. Each project would require a total investment of about $20 billion. According to government estimates, the blocks could contain at least 12.5 billion barrels of recoverable reserves, and the three projects could eventually produce a combined 1.2 million bbl/d of crude oil. In February 2010, the Venezuelan government announced the results of the bid round. A consortium headed by Repsol YPF had secured Carabobo 1, while a consortium led by Chevron had secured Carabobo 3. The second project, Carabobo 2, went unawarded. "

There is a difference between these two reports. They agree the company Chevron is in Venezuela trying to do business. Therefore your comment that Venezuela doesn't want "western imperialists" is wrong. Or maybe you consider Chevron to be a good western imperialist? The two reports also have a difference in the date this request for bids started. The Venezuelanalysis says in late 2009, and the EIA says October 2008. I think the EIA is more likely to be right. The difference, my guess, is inefficiency in making this work, which is so common in the way the Venezuelans do things. They are slow, and they do not accomplish things, and this is what is happening to their oil production.
