  2. Definitions . 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 IWOOD2002 - Uppsala, 24.05.2002

  25. 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 increase IWOOD2002 - Uppsala, 24.05.2002

  26. 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 IWOOD2002 - Uppsala, 24.05.2002

  27. Conclusions - External Supplies • Russia (gas / oil) • Northern Africa (gas / oil) • Middle East (oil / gas?) • Caspian (oil / gas?) • Western Africa (oil) IWOOD2002 - Uppsala, 24.05.2002
