Annotation:

The authors of the article consider the problem of optimizing the development of gas and gas condensate fields by maintaining the required operational conditions to ensure uniform distribution of reservoir pressure throughout the reservoir. Using the dynamic specific drainage volume of a reservoir, an equation was derived expressing the relationship between the bottomhole pressure for each well of a gas condensate reservoir and the reservoir pressure in the well’s area, based on cumulative gas production data and the magnitude of the reservoir pressure change in the well’s area.

The resulting equation forms the basis for determining optimal bottomhole pressures for wells, taking into account well filtration resistance coefficients, to ensure uniform reservoir drainage and efficient use of reservoir energy. This equation can be used to determine optimal well bottomhole pressures when calculating field development indicators using hydrodynamic and integrated models.
