Report summary

OML 119 is located in the southeastern Niger Delta, approximately 50 kilometres offshore. The two producing fields on the block, Okpoho and Okono, were discovered by the Nigerian Petroleum Development Company (NPDC) in 1978 and 1983 respectively. Despite encouraging well results, the fields' development did not start until 2001, when Agip Energy and Natural Resources (AENR) signed a modified service contract with NPDC. The project, located in shallow water, utilises an FPSO which is more commonly deployed in deep water. The Okono field produces oil from subsea wells tied-back to the Mystras FPSO located at the field. Oil from Okpoho is produced via a platform linked to the FPSO by pipeline. Oil is exported from the FPSO by shuttle tanker. During 2008, the partners purchased the FPSO Mystras, and there are plans to upgrade its capacity. Wood Mackenzie understands significant reserves upside still exists on the Okono and Okpoho fields.
