Enterprise Oil announces Nelson Field equity settlement

Enterprise Oil announced today that the Nelson field owners have reached a
final agreement on field equity. This Agreement, which has received the
approval of the Department of Trade and Industry (DTI) and is effective 1
April 2000, provides that equity is now fixed for the remainder of the field's
life, so eliminating any future costly and time-consuming redetermination
processes.

Nelson is one of the North Sea's most prolific producing fields, having
produced 290 million barrels since first production in 1994 and is still
consistently averaging over 100,000 barrels of oil equivalent on a daily
basis. 

Peter Kallos, General Manager - UK commented: 'I am delighted that
co-venturers were able to support this initiative which will enable Enterprise
to implement the forward infill drilling programme in a spirit of real
co-operation and to deliver the very best future returns for all field
owners.'
