Russian authorities said they were able to control an oil spill from the Trebs oil field in the arctic two days after a leak was reported. \"An accident occurred at the oilfield at 5:30 p.m. Moscow time on Friday, oil began rushing,\" a spokesman for the regional Emergencies Ministry was quoted by Russia\'s state-run news agency RIA Novosti as saying. \"Rescuers arrived on Saturday and the rush of oil was terminated on Sunday.\" Trebs and the nearby Titov deposits are among the most lucrative in a region just south of the Pechora Sea. Moscow estimates the region contains as much as 1 billion barrels of oil. Russian energy company Lukoil has invested about $1 billion to develop the region. It signed an agreement last year with Russian oil company Bashneft to develop the fields. The Russian report didn\'t provide a spill volume or indicate how the spill was controlled. There was no fire reported and nobody was injured.
