Total combined reserves
At Nostrum, we have an outstanding track record of converting reserves. An updated reserve report by Ryder Scott, as at 1 January 2018, has shown 488 mmboe of proved and probable reserves for the Chinarevskoye and adjacent Trident fields. In line with our strategy, we will continue to look to increase our reserve base and secure production growth.

Contingent resources
In addition to the estimated 2P reserves, contingent resources have been identified in the Chinarevskoye, Rostoshinskoye, Darjinskoye and Yzhno-Gremyachenskoye licence areas.
