In the next few decades the E&P Industry will face a unique confluence of two major challenges: it must continue to provide the world with sufficient oil and gas to support global development, while at the same time help it reduce the environmental impact of fossil fuel use, with a focus on the reduction of green-house gas CO2 emissions. This calls for innovative technical solutions and new approaches to the design and management of increasingly interdependent energy- and CO2 value chains.

The "intelligent" capabilities that the industry has developed over the past decade can be leveraged to meet these twin challenges. The combination of CO2 EOR with Carbon Capture and Sequestration (CCS) in particular, offers attractive opportunities to combine enhanced oil- and gas recovery with GHG reduction, in a profitable way. This can be done at the level of individual field developments but also at the level of integrated energy/CO2 systems.

The technical and economic implications of an "eco-efficient" approach to the design of CO2 EOR projects are discussed, taking a North-Sea EOR feasibility study and CO2 supply project example. These types of projects greatly benefit from "oilfield intelligence" to improve ultimate recovery and optimize CO2 capture, use and storage.

It is concluded that eco-efficient and intelligent technical and commercial design will have to become a core capability of the E&P Industry.
