     Shell Quest proposes to use deep geological storage – that is, injecting liquified CO2 roughly 2,300
     metres below Earth’s surface. Dense rock layers called cap rock which are located above the targeted
     CO2 storage formation would ensure that the CO2 stays underground. The transportation, injection
     and storage of CO2 in geological formations would use existing technology that has been practiced
     safely and reliably for many years by the oil and gas industry in acid gas disposal and enhanced oil
     recovery projects in Canada, the United States and around the world. This is discussed in more detail
     in the section entitled “Safety”.

     Other Large CCS Projects

     The oil industry has used CO2 to obtain incremental barrels from mature oil fields for many years.
     In Canada CCS has been used in the Weyburn oilfield in Saskatchewan since 2000. The Weyburn
     Project uses a 330-kilometre pipeline to transport carbon dioxide captured at the Great Plains Coal
     Gasification plant, which manufactures methane from coal near Beulah, North Dakota. Weyburn
     is one of four large-scale CCS projects in operation around the world and stores about 1.5 million
     tonnes of CO2 each year.

     The In Salah CCS project in Algeria extracts roughly 1 million tonnes of carbon dioxide each year
     from a natural gas stream and injects it deep underground. The injected CO2 helps maintain reservoir
     pressure, enabling the producer to recover more natural gas from the reservoir.

     The other two existing large CCS projects are located off the shores of Norway. The Sleipner project
     in the North Sea and the Snøhvit liquefied natural gas facility in Norway’s Arctic extract carbon
     dioxide from natural gas during production and return it to deep formations under the sea.

     A report from the environmental group The Pembina Institute said, “Carbon capture and storage is one
     way to reduce greenhouse gas emissions associated with oil sands development, provided it is done
     in a responsible manner and efforts are also made to minimize the use of energy and promote energy
     efficiency in all aspects of an operation.”

       Storage: Shell proposes to inject the CO2 deep underground into a geological formation known
       as the Cambrian Basal Sands at a depth of 2,000 – 2,500 metres. This formation is deeper than
       the oil and gas deposits in the area and is roughly 2,000 metres below any freshwater aquifers.
       The injection sites are anticipated to be within 60 kilometres of the Scotford Complex.

     Shell will undertake public consultation in a variety of ways, including workshops and open house
     forums, for example, and one-on-one meetings with those living nearby. In addition the company will
     distribute and otherwise make available information, such as this Public Disclosure Document from the
     Energy Resources Conservation Board, and other third-party information about CCS.

     Shell encourages the public to participate in the consultation process, since such participation provides
     the avenues by which concerns can be expressed and appropriate actions taken. This results in more
     successful projects.
