Nigerian president signs bill amending offshore oil output act

LAGOS, Nov 4 (Reuters) - Nigeria's President Muhammadu Buhari signed into law on Monday a bill that amends legislation on agreements related to offshore oil production, according to the president's Twitter account.

While offshore oil projects are among the most challenging for companies to develop, they have helped boost oil output in the last few years from Nigeria, Africa's top crude producer.
