Proved reserves established in a yet non developed reservoir that can be in proximity to or juxtaposed with a reservoir in which there are proven, developed and producing reserves. Proved undeveloped reserves are those proved reserves that are expected to be recovered from future wells and facilities, including future improved recovery projects. Under the new SEC rules (end 2009), Proved Undeveloped Reserves may be classified as proved undeveloped if there is a high degree of confidence that the quantities will be recovered
