Afren in Nigeria
We have nine assets within Nigeria, spanning the full cycle E&P value chain right through from exploration, appraisal and development to production.
Afren achieved first oil production in Nigeria through development of the Okoro field, which was successfully commissioned in June 2008. In a demonstration of the Company’s technical and financial capabilities, the two-year lead time from farm-in to first oil represents one of the fastest developments of an oil field in Nigeria by an independent to date. The field today continues to outperform pre-development expectations, there being a firm focus now on maximising the economic recovery factor at the field through infill drilling, prudent reservoir management and efficient operational delivery.
Our near-term organic growth in Nigeria will be driven primarily by the Ebok/Okwok/OML 115 complex, located offshore south east Nigeria. We farmed into the Ebok field in early 2008, and acquired stakes in Okwok and OML 115 in August 2009 and January 2010 respectively. We have achieved a 100% appraisal drilling success rate in the area to date, and NSAI has increased its total 2P recoverable reserve estimates at Ebok to 107.5 mmbbls. We expect first production from Ebok in October 2010.
At each asset we have forged vital partnerships with indigenous companies and are over 90% staffed locally in our Nigerian office. We place community relations at the heart of what
we do in Nigeria, where we have a full team dedicated to and constantly engaging with our local host communities. We are committed to delivering sustainable benefits to people in the local communities that have a long-lasting and positive effect.
