BAGHDAD, Feb 19 (Reuters) - Iraq's oil reserves have increased to 153 billion barrels, from a previous estimate of 143 billion barrels, Oil Minister Jabal al-Luaibi said on Sunday.

Iraq will ask the Organization of the Petroleum Exporting Countries to adopt the new figure as the official estimate for its reserves, he said in a statement.

The increased estimate is the result of appraisals and exploration carried out at seven oil fields in central and southern Iraq, he said.
