ACQUISITION OF INTEREST IN COLUMBUS FIELD EXTENSION

London, 27 October 2015 - Serica Energy plc (AIM: SQZ) is pleased to announce that agreement has been reached with BG International Limited ('BG') and SSE E&P UK Limited ('SSE') for BG and SSE to transfer their equity in that part of Block 23/21a which contains an extension to the Columbus field (the 'Block 23/21a Columbus Subarea') to the Block 23/16f participants, Serica Energy (UK) Limited, Endeavour Energy UK Limited and EOG Resources United Kingdom Limited (the 'Columbus Participants'), for a nominal sum. The transaction is subject to the consent of the Licensing Authorities, and is in the spirit of the Oil & Gas Authority's ('OGA') commitment to expediting UK offshore oil and gas field developments.

Highlights

· Serica's contingent resources attributed to the Columbus Field increase by 50% to 7.8 mmboe *

· Greater autonomy for the Columbus participants

· Discussions on infrastructure access expected to move forward under the guidance of the OGA

Block 23/21a Columbus Subarea lies directly south of Block 23/16f. The BG and SSE interests in the Block 23/21a Columbus Subarea are being transferred to the Columbus Participants in proportion to the interests held by the Columbus Participants in Block 23/16f. Following completion of the transaction, the Columbus Participants will own 100% of the Columbus field with Serica having a 50% interest and continuing as field operator. As well as increasing the Columbus Participants' share of the total Columbus field, the transaction provides the Columbus Participants with greater autonomy, and the ability to push the project forward without the encumbrance of unitisation.

The development of the Columbus field is contingent upon access to infrastructure being agreed on a commercial basis with nearby infrastructure owners, and discussions are now expected to move forward under the guidance of the OGA. An extension has been granted to the licence terms covering Block 23/16f to enable agreement on an export route to be reached and a field development plan to be submitted. A similar extension is expected to be granted in respect of the Block 23/21a Columbus Subarea licence.

Tony Craven Walker, Chairman commented:

"This transaction, along with the improved performance of the Lomond platform in recent months, one of a number of potential hosts, has given Serica encouragement that a cost effective offtake route can be found for Columbus. There is the added benefit that future production from Columbus could help extend the life of other fields and facilities in the area, including the Erskine field in which Serica has an 18% interest. I would like to acknowledge the OGA's role in helping to unlock the potential of the Columbus project and to thank BG and SSE for cooperating with the Columbus Partners to reach this agreement."
