Everyday, through our Upstream production activities, we provide the energy for a better life for millions of people.
Our portfolio is very diverse in terms of maturity of fields, but most of them are mature fields, which have been producing for decades.
Operating fields which have a long production history comes with challenges: increasing the recovery rates and dealing with low productivity per well, while controlling costs. Production decline is natural in mature fields and high investment is needed to mitigate this decline.
Hydrocarbon production in a field can go through three stages, as the field matures:
- Primary production: This is used in newer fields, when there is still pressure in the reservoir and oil and gas naturally rise to the surface
- Secondary recovery (improved recovery): Specific technologies are used when hydrocarbons from a reservoir no longer flows to the surface and several technologies like water and gas injection are used to increase reservoir pressure.
- Tertiary recovery (enhanced recovery): Specific technologies are used to further increase oil production from a reservoir, after the first two stages. These technologies are more expensive to employ on a field.
According to our 2021+ strategy, we aim to maximize economic recovery from our fields, by increasing the recovery rate from 25% to 28% for our oilfields and from 50% to 55% for our gas fields.
