Venezuela has announced a string of deals with oil companies and the first oil field bidding round since Chavez took office in 1999, and industry sources report a marked change in tone from last year's wave of takeovers.
State oil company PDVSA may be seeking to stem growing cash flow and operational problems, only months after a wave of nationalizations that drove out two of the world's biggest energy companies.
One oil sector contractor who asked not to be identified said PDVSA this year has been speeding up contract talks.
"Last year they were telling me, 'You'll never see this work again' -- and now it's all about extending contracts and negotiating rate increases," he said.
This year alone, PDVSA has signed deals with Royal Dutch/Shell, Total and Statoil for oil-field studies.
Market observers say Venezuela's output is around 25 percent below official production figures of 3.2 million barrels per day, while exports to the United States of refined products tumbled last year amid chronic refinery outages.
Venezuelan central bank figures show oil-sector GDP, which measures activity in oil production, processing and transport, shrank 5.3 percent last year despite record income at PDVSA and borrowing of close to $13 billion in 2007.
Analysts say PDVSA's resources are being stretched thin by enormous social spending obligations that now include importing and distributing food to ease nagging shortages of groceries.
