             SERICA ENERGY PLC ANNOUNCES SALE OF LEMATANG INTEREST


London, 13th June 2006 - Serica Energy plc (TSX Venture: SQZ; AIM: SQZ)
announces that it has concluded an agreement for the sale of its 10% interest in
the Lematang Production Sharing Contract, onshore south Sumatra, to Lundin
Petroleum AB ('Lundin Petroleum') for US$5 million in cash subject to the
required partner and Indonesian government approvals. The block includes the
nearly depleted Harimau gas field and the Singa gas field development project.
As at 31 December 2005 the net book value of the assets disposed of was US$2.4
million, with attributable turnover and profit for the year ended 31 December
2005 of US$0.1 million.


Paul Ellis, Chief Executive, commented:


'Given our focus on the development of Serica's operated Kambuna and Tanjung
Perling fields offshore Sumatra, Lematang was no longer a core asset due to the
small level of working interest that we held. Following the disposal of this
interest Serica also holds operatorship of all its assets in Indonesia, the UK
North Sea and Spain.  The proceeds from this sale will be deployed effectively
in other parts of Serica's portfolio, such as the Kambuna Field, which is due to
come on stream in 2008, and where we recently increased our holding from 55% to
65%.'
