Feb 5 (Reuters) - Royal Dutch Shell's output in the top U.S.
shale field reached about 250,000 barrels per day in December,
the company's Permian head said on Wednesday.
Shell plans to spend about $3 billion per year for the next
five years on shale projects, said Amir Gerges, vice president
of Permian assets for Shell, at the Argus Americas Crude Summit
in Houston.
