"Of course we want our quota increased, just like every other member of OPEC," said Lukman, who is also OPEC president. "We will make our case accordingly. When it is the appropriate time, we are going to present our data, facts, figures and justification for a quota increase," he said.

"We don't have any specific date that we are tabling our request. If you don't want to prejudice your position on this issue, you talk less because every member of OPEC is agitating for quota increase." OPEC ministers are due to meet on September 19 to consider oil output policy for the fourth quarter.
