Giants - oil and gas fields with more than 500 million boe in reserves - are no longer a thing of the past. Just before we went to print, BP announced the discovery of possibly 3 billion barrels in the Gulf of Mexico. That's a giant six times over. A few weeks ago it also became known that Iran has made its largest oil find in five years, according Oil Minister Gholamhossein Nozari. More than 8.8 billion barrels of crude oil has reportedly been discovered in the Sousangerd oilfield in the Zagros Mountains, in southwestern Iran, almost next to Iraq. In-place gas reserves discovered in the oil field stand at 11 Tcf, also quite impressive.
