Background: Recent years have brought new understanding of cost efficient reservoir processes for water based enhanced oil recovery. Some of these new techniques have internationally been applied in on shore fields and created significant value for the owners and the society. Offshore application is still in its infancy, but, studies predict interesting combined increased potential of 5-10%. Offshore application creates extra ordinary challenges related to handling, eventual back production and discharge to sea of these chemicals. These risks needs to be assessed and handling requirements established. The economic impact of implementation of such techniques can be tremendous for both the field owners and the Norwegian society.
The chemicals involved are basically polymers, cross linkers and surfactants
Project goals: Environmental impact and risk assessment related to utilization of EOR chemicals during platform operations reservoir flow and discharge of produced water. Recommend guidelines for safe and environmental offshore handling of EOR chemicals .
Identify and characterize chemical properties and their environmental impacts for the most cost efficient EOR chemicals on the market today. Assess hazards and environmental challenges related to handling, injection, reservoir processes, back production and discharge to see. Develop guidelines for handling and utilizations through the offshore implementation value chain.
Deliveries: A report outlining chemical characteristics of representative EOR chemicals, major risks associated with offshore applications and guidelines for safe and environmental friendly operations.
