CONT: With reference to the amount of oil or gas in a field or reservoir there are three ways in which reserves may be be expressed. Proven reserves are assessed from reliable geological and well engineering data. Probable reserves are undeveloped reserves that are considered to be recoverable, by secondary recovery methods if necessary. Possible reserves may be recoverable from untested formations, for example, by drilling deeper.
