There is enough research work on the effective use of non-hydrocarbon gases in order to increase the component recovery of hydrocarbon deposits. Over a long period, we have also carried out a number of research works on the effect of nitrogen and carbon dioxide on the final condensate recovery factor of fields, as well as on the productivity of gas condensate wells.
However, it is known that the formation systems of gas condensate fields, along with other non-hydrocarbon gases, contain nitrogen and carbon dioxide. Sometimes their number has a rather large share in the total volume. But, the effect of the amount of nitrogen and carbon dioxide naturally present in reservoir systems on the final condensate recovery coefficient of gas condensate fields has not been studied enough.
The influence of the amount of nitrogen and carbon dioxide in the composition of reservoir systems on the condensate recovery coefficient of gas condensate fields has been studied. To this end, a multicomponent hydrodynamic model of the Bulla-Sea field was used as a base case, the factors influencing the process were studied by comparing the final condensate recovery coefficient of the field with other systems containing nitrogen and carbon dioxide.
