                           £60m contract for COGAP

Burlington Resources Inc has announced the signing of a £60 million contract
for a gas compression and treatment plant at Barrow-in-Furness, Cumbria, with
Costain Group PLC ('Costain').  Project management, detailed engineering, 
procurement of components and construction are included in the contract, which 
will be performed by Costain Group division, Costain Oil, Gas & Process Ltd.


The plant is part of the development of the Rivers Fields in the East Irish
Sea, which are estimated to contain recoverable resources of between 350 and
400 billion cubic feet of natural gas. Work on the plant will begin shortly
and is expected to be completed by around the end of 2003. Offshore gas
production is expected to reach approximately    120 million cubic feet per
day in 2004.


The Rivers Fields, which are named after British rivers, are located in the
East Irish Sea between the British mainland and the Isle of Man.  The nearest
field to shore is approximately 12 miles west of the English coast and 24
miles north of the Welsh coast.  Burlington Resources' total investment in the
Rivers Fields project will be approximately £185 million.
