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. The 1C+2C contingent resources estimated as of 1 January 2018 for the Chinarevskoye area amount to 105.4 million barrels of liquids and 419.5 billion cubic feet of sales gas. For the three additional licences the contingent resources amount to 12.7 million barrels of liquids and 202.5 billion cubic feet of sales gas.
