Proven Reserves
Definition of 'Proven Reserves'After an oil exploration firm conducts a seismic survey on a piece of land, it obtains the proven and probable reserves in that area. Proven reserves are those which have an over 90% chance of being present. For example if a oil company believes that there is good chance of a successful drilling operation, they would classify those reserves as "proven." |

Investopedia explains 'Proven Reserves'If a reserve is considered to be proven, this does not guarantee a successful operation. After the total reserves of a piece of land are determined, the oil company makes a decision whether or not to pursue drilling. The initial seismic test is considered a sunk cost.Total Reserves = Proven + Probable (unproven) |
