Reserves• hydrocarbon quantities proven in fields• can be produced economically with current technologies
.
Resources• geologically identified hydrocarbons which can’t be economically produced under present conditions
• unidentified but expected hydrocarbons due to geological reasons in equivalent regions (yet to find)
Hereby we consider for resources as well as for reserves the recoverable amount

Conclusions - Oil• North Sea is a mature oil province• peak production occurred in 2001• reserves underestimated ?• annual production decline will be
> 5 %• accordingly, western Europe‘s oil
import dependance will increaseIWOOD2002 - Uppsala, 24.05.2002

Conclusions - Natural Gas• North Sea is a mature gas province• annual production is still increasing• peak production in front - 2005 ?• production can be kept stable for
another 1 – 2 decades
• But: due to the increase in demand, western Europe‘s import dependance will rise
