OPEC, oil companies clash at Davos over price collapse

OPEC defended on Wednesday its decision not to intervene to halt the oil price collapse, shrugging off warnings by top energy firms that the cartel's policy could lead to a huge supply shortage as investments dry up.

The strain the halving of oil prices since June is putting on producers was laid bare when non-member Oman voiced its first direct, public criticism of the Organization of the Petroleum Exporting Countries' November decision not to cut production but instead to focus on market share.
