Proved oil and gas reserves

The tables present oil and gas reserves on a net basis which means that they include the reserves relating to (i) the Shell subsidiaries excluding the reserves attributable to non-controlling interest holders in our subsidiaries and (ii) the Shell share of equity-accounted investments. Proven minable oil sands reserves are reported separately for 2008. As a result of SEC rule changes, these proven minable oil sands reserves have been converted to synthetic crude oil proved reserves and from 2009 onwards these are included in the proved oil and gas reserves. Moreover, from 2009 onwards bitumen proved reserves are reported separately. In previous years, the bitumen proved reserves were included in the reported proved oil and gas reserves in Canada.
