Abstract
The Norwegian North Sea Brage field came on production in Sept. 1993. The field is currently producing approx. 6000Sm3/d and is on decline from its plateau rate of 19400Sm3/d. Drilling new production infill wells has increased production and has shown to be an effective way of prolonging the life of the Field. Learning from past well results has helped to improve methods. The main difficulty in this process is to accurately evaluate the success of well results. Statistics have been used to show trends and give an indication when variations occur. A detailed evaluation of well planning and well results was undertaken to demonstrate the value of specific geological and geophysical methods. Two examples from the Barge field are presented where the value of improved geophysical methods were estimated.
