"As the CEO, I'm responsible for the global business of Halliburton in both hemispheres and I will continue to spend quite a bit of time in an airplane as I remain attentive to our customers, shareholders and employees around the world," Lesar said. "Yes, I will spend the majority of my time in Dubai."
Lesar's announcement appears to signal one of the highest-profile moves by a U.S. corporate leader to Dubai, an Arab boomtown where free-market capitalism has been paired with some of the world's most liberal tax, investment and residency laws.
"The eastern hemisphere is a market that is more heavily weighted toward oil exploration and production opportunities and growing our business here will bring more balance to Halliburton's overall portfolio," Lesar said.
In 2006, Halliburton -- once headed by Vice President Dick Cheney -- earned profits of $2.3 billion on revenues of $22.6 billion.
More than 38% of Halliburton's $13 billion oil field services revenue last year stemmed from sources in the eastern hemisphere, where the firm has 16,000 of its 45,000 employees.
Cheney was Halliburton's chief executive from 1995-2000 and the Bush administration has been accused of favoring the conglomerate with lucrative no-bid contracts in Iraq.
Federal investigators last month alleged Halliburton was responsible for $2.7 billion of the $10 billion in contractor waste and overcharging in Iraq.
Halliburton last month announced a 40% decline in fourth-quarter profit, despite heavy demand for its oil field equipment and personnel.
