(1) There is no certainty that any portion of the resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources. Prospective resources are those quantities of oil estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective resources have both an associated chance of discovery and a chance of development. For the purposes of the NSAI Report, the volumes and parameters are associated with the best estimate scenario of prospective resources. Prospective resources are the arithmetic sum of multiple probability distributions. Unrisked prospective resources are estimates of the volumes that could reasonably be expected to be recovered in the event of the discovery and development of these prospects.
