Total's Egina field achieved first oil in December.
At its peak, the field will increase Nigeria's production by 10% in 2019.
However, under OPEC's 1.2million production cut agreement, Nigeria is expected to keep OIL production at 1.738mln/day (excluding other liquids).
The development will take Nigeria's total liquid (crude oil, condensate etc) above 2.1mln b/day in 2019.
This is still below the proposed budget benchmark of 2.3mln b/d.
