Muammar Gaddafi As Libya's new rulers consolidate their grip on the country, the big oil majors are circling the nearly liberated, petroleum-rich country.
Italy's ENI and France's Total have long histories of operating in the country and are leading the charge, while UK giants BP and Royal Dutch Shell are further back in the queue, being at the stage of exploring for oil there rather than producing it.
Vallares, the company headed by former BP chief executive Tony Hayward, which has about US$2.1 billion of cash to spend, has also said it could be interested in Libya.
Oil companies are anxious that deals made with Muammar Gaddafi's Government after former British Prime Minister Tony Blair smoothed the way will still stand under the interim Transitional National Council (TNC) set up by the rebel forces.
BP began drilling its first exploration well in February but shortly afterwards suspended operations and evacuated its staff. A spokesman said: "We have the contract and we haven't seen anything that says we are not welcome. But we need to build a relationship with the new government.
