March 19 (Reuters) - U.S. oil production will grow to

exceed 14 million barrels per day and then plateau,

ConocoPhillips ( COP ) CEO Ryan Lance forecast on Tuesday.

Output in the top U.S. shale field, the Permian basin of

West Texas and New Mexico, will rise between 300,000 bpd and

400,000 bpd this year, he said in remarks at the CERAWeek energy

energy conference.

Construction of the company's $8 billion Alaskan oil

development project, called Willow, is fully underway and will

take four years to complete, he said.
