Gabon: Affanga Deep Well Result

London, 27 May 2014: Ophir Energy plc ("Ophir" or "the Company") announces that drilling operations have now concluded on the Affanga Deep-1 well in the Gnondo Block offshore Gabon. Ophir has a 100%* operated interest in the Block.

The well was drilled by the Vantage Titanium Explorer drillship to a depth of 4,240m TVDSS and was targeting a number of reservoir intervals of Turnonian and Cenomanian age. The well encountered thinner than expected sandstone sections with poor reservoir characteristics. Gas and indications of liquids were encountered during drilling but significant hydrocarbon shows were not encountered in the target formations.

Cuttings have confirmed the presence of a Cenomanian oil prone source rock which may have positive implications for the prospectivity of the wider Ogooué Delta outboard play and for the Deepwater play to the west of this location. Log and cuttings analysis is continuing.

The rig will now move to spud the pre-salt Okala prospect on the Mbeli Block. The Okala-1 well is expected to take approximately 40 days to complete.

*OMV farm-in for a 30% net interest is subject to Government approval
