Nigeria’s Guaranty Trust Bank and a subsidiary of Royal Dutch Shell have granted a $270 million loan to independent Nigerian oil and gas producer Amni International, Reuters reports.

The terms of loan will give Shell Western Supply and Trading sole access to the 16,000 barrels per day (bpd) of oil the company pumps in two fields off Nigeria’s oil-rich Delta region.

Production at offshore fields, including Amni’s Ima and Okoro/Setu, is difficult to maintain, but Amni said the loan would allow them to further develop the fields. The company also has an offshore concession in Ghana.
