                  BP TO SELL GYDA FIELD INTERESTS TO TALISMAN


BP announced  today that it has agreed to sell its 61 per cent operated share of
the Gyda field for $90 million in a cash  transaction  to Talisman  Energy Norge
AS, a wholly owned subsidiary of the Canadian based company Talisman Energy Inc.

The sale has an  effective  date of 1 January  2003 and is subject to  Norwegian
regulatory consent and other approvals.  The companies expect that the deal will
be completed by 4Q 2003.

The  transaction  also includes BP's share of the Gyda gas pipeline and its full
45 per cent share of the adjacent exploration license PL 019 C.

The Gyda field's  remaining  gross booked  recoverable  reserves at January 2003
were 23.2 million barrels of oil equivalent  (boe).  Current gross production is
approximately 13,000 boe per day.

Scott Kerr,  head of BP's Norwegian  Business Unit said: "We are pleased to have
reached this  agreement  with  Talisman.  Talisman is a global  operator  with a
proven track record of acquiring  producing  fields and focusing  operations  to
improve performance and increase field life.

"The  admission of a new entrant into the Norwegian  Continental  Shelf can only
benefit the province as it matures.  This is also aligned with the desire of the
Norwegian authorities to have a greater diversity of companies to the region. We
will provide all necessary  assistance to Talisman and the employees to ensure a
safe and smooth transfer of Gyda."

BP remains  committed to Norway with significant  investments in the Valhall and
Ula  fields,  and is also a partner in Ormen  Lange and  operator  for the Skarv
field development.  The company was awarded exploration acreage in Norway's 17th
licensing round in 2002 and expects to participate in the 18th round.


Notes to Editors:

- The Gyda field is located in the Southern  part of the North sea in block 2/1,
  license  019B.  The  license was awarded in 1965 and the field came on stream
  in 1990.

- Total recoverable reserves were 225 million barrels of oil, 5.8 billion cubic
  metres of gas and 26 million barrels of condensate. Other partners in the
  Gyda field are DONG (34 per cent) and AEDC (5 per cent).
