It wasn't that long ago that when oil breached the $30 a barrel mark, OPEC was lamenting the high price was bad for business and the world. Now, about 3 years later, more than double that "ridiculously high" level is not enough.
Opec oil producers warned on Tuesday that low oil prices have created a crisis situation that threatens key investment in production, pushing them to seek moderate price increases by cutting output.

Qatar's energy minister, Abdulla bin Hamad Al Attiyah, defended Opec's decision last week to cut production by 1.5 million barrels a day, saying it was necessary amid falling demand due to the global economic turmoil.

United Arab Emirates energy minister Mohammed Bin Dhaen al-Hamli said the current low prices were "very dangerous for the world's economy."

"We need an adequate, reasonable oil price that will continue to stimulate investment," he said. "I think this is really a crisis situation and I think it is very difficult to predict what's going to happen."

Opec secretary-general Abdullah El-Badri said the organisation was not seeking a high oil price, but a moderate rise. Al Attiyah said a price of between $70 and $80 a barrel was reasonable.
