Saudi Arabia’s Oil Minister Ali al-Naimi revealed that the prices of crude oil are constant and it has been expected by producers that the prices will increase in 2010.

He said in an interview at a conference in the Qatari capital Doha today, “Oil demand is very good. It is going to increase this year”.

Abdalla Salem El-Badri, the group’s Secretary General shared that organization of Petroleum Exporting Countries members should follow oil-production levels approved in 2008 even if the demand inflates.

A conference will be hosted by the Organization of Arab Petroleum Exporting Countries, which includes seven of OPEC’s 12 members. Ministers from Arab oil-producing nations will gather in Doha from today to May 12 for the same.

This week, oil prices declined 13%, which is the biggest drop, since December 2008, because the gasoline inventories of the U.S. exceeded seasonal norms and Europe battled with a Greek debt crisis, which is expected to slow down the pace of economic recovery, as well as demand for crude.

Qatar’s Oil Minister Abdullah al-Attiyah and Algeria’s Oil Minister Chakib Khelil revealed that the Greek situation is putting pressure on oil prices. On May 3, oil rose to an 18-month high of $87.15 and settled at $75.11 in New York last week. Since March 17 when OPEC agreed to uphold existing output quotas for a fifth time since 2008, prices are down 9%.
