Definitions of PRODUCIBLE in various dictionaries:

Proven reserves, also called measured reserves, 1P, and reserves, are industry specific terms regarding fossil fuel energy sources. They are defined as a "Quantity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering data, to be recoverable from well established or known reservoirs with the existing equipment and under the existing operating conditions." A reserve is considered a proven reserve if it is probable that 90% or more of the resource is recoverable while being economically profitable. These terms relate to common fossil fuel reserves such as oil reserves, natural gas reserves, or coal reserves. Operating conditions are taken into account when determining if a reserve is classified as "proven". Operating conditions include operational break-even price, regulatory and contractual approvals, without which the reserve cannot be classified as proven. Price changes therefore can have a large impact on the classification of proven reserves. Regulatory and contractual conditions may change, and also affect the amount of proven reserves. If a reserve's resources can be recovered using current technology but is not economically profitable it is considered "technically recoverable" but cannot be considered a proven reserve. Reserves less than 90% recoverable but more than 50% are considered "probable reserves" and below 50% are "possible reserves".
