MOSCOW, April 19 (Reuters) - Gazprom Neft SIBN.MM , the oil
arm of Russia's gas giant Gazprom GAZP.MM , will delay the
start of commercial production at huge Novoportovskoye oilfield
by around six months, company sources told Reuters on Tuesday.
The company had planned to produce 2.5 million tonnes of oil
at the field this year.
"The production will be less than that," one source said.
