Maureen - Conclusions Maureen - Conclusions
COCO2 2 and water injection increased oil and water injection increased oil recovery by 5-10%recovery by 5-10%
This represents up to 1billion pound This represents up to 1billion pound revenue from increased oil production revenue from increased oil production while storing over 55 million tonnes of COwhile storing over 55 million tonnes of CO22
This is equivalent of all the COThis is equivalent of all the CO2 2 produced produced from all activities from the population of from all activities from the population of London in a yearLondon in a year
In the future, these strategies could be In the future, these strategies could be applied to other North Sea fields applied to other North Sea fields
