Shell oil says pumping has resumed from a bombed pipeline in southern Nigeria - but says production is still reduced and that it can not yet meet delivery commitments.
Dutch-based Shell declared a "force majeure," a technical release from its contracts, after last Tuesday's attack in the Niger Delta region. The pipeline bombing killed at least eight people, set off huge fires, and cut oil output by 180,000 a day.
Shell says repairs are in progress but that daily production is still down by at least 15,000 barrels.
Nigeria's President Olusegun Obasanjo declared a regional state of alert after the attack, for which a previously unknown group claimed responsibility.
Many Delta residents complain they receive little benefit from the oil fields, which generate huge revenues for corporations and the Nigerian government.
