              Serica Energy Plc announces proposed Equity Offering

Serica Energy plc ('Serica', or the 'Company') announces an offering of Ordinary
Shares of Serica ('the offering') which will be offered for sale by way of a
private placement in the United Kingdom and pursuant to a short form prospectus
in the Canadian provinces of British Columbia, Alberta, Saskatchewan, Manitoba
and Ontario. A receipt has been received by Serica for the preliminary short
form prospectus filed on December 10th 2007.

The offering consists of new Ordinary Shares by the Company. Pricing is expected
to take place on or about December 12, 2007. The Company's intended use of
proceeds from the offering of Ordinary shares is to support its exploration and
field appraisal drilling programmes in 2008/9 in South East Asia, the UK,
Norway, Spain and Ireland.

JPMorgan Cazenove is sole financial adviser, sole bookrunner, joint underwriter
and co-manager for the offering. Tristone is acting as joint underwriter and
co-manager for the offering.  JPMorgan Cazenove and Tristone have agreed,
subject to the terms and conditions of a placing agreement between JPMorgan
Cazenove, Tristone and Serica (the 'Placing Agreement'), to use their reasonable
endeavours to procure subscribers for the Ordinary Shares.

Due to the intended size of the placing, shareholder approval will be sought to
disapply (under section 95 of the Companies Act 1985), statutory rights of
pre-emption. Accordingly, a circular is expected to be sent to the Company's
shareholders shortly to convene an extraordinary general meeting ('EGM') at
which a special resolution will be proposed to disapply these statutory
pre-emption rights and ordinary resolutions will be proposed to increase the
Company's authorised share capital and confer authority to allot the new
Ordinary Shares. Completion of the placing is also subject to certain customary
conditions, including regulatory approval from the relevant securities
regulators in Canada, and on the terms of the Placing Agreement becoming
unconditional in all respects.
