A real choice exists today on a number of discoveries between platform-based or subsea development solutions. Statistics from the Norwegian continental shelf (NCS) show that fields developed with fixed platforms have a substantially higher recovery factor. The potential for a later commitment to...

The decline in oil prices, combined with high costs which are slow to deflate, has brought forward the date when some fields on the Norwegian continental shelf (NCS) will cease production. Measures are therefore urgently required to extend the producing life of these fields and to improve their...

Drilling expenses has increased sharply in recent years. The productivity of drilling operations - in terms of meters drilled per day - significantly influences exploration costs. This study analyzes the effect of different types of learning on offshore drilling productivity. The econometric...

What would be the effect of CO2 pricing on global oil supply and demand? This paper introduces a model describing the interaction between conventional and non-conventional oil supply in a Hotelling framework and under CO2 constraints. The model assumes that non-conventional crude oil enters the...
