Key words: regressive depression of seabed, subsidence of surface, gas influx modeling, electric analog, Shtokman gas and condensate field.
The paper focuses on one of the methods to determine regressive depression of seabed, resulting from development operations in Shtokman gas and condensate field, which involved gas influx modeling with the help of electro-hydrodynamic analogy. The suggested method corresponds to the 3-phase reservoir development plan for 72 wells for a period of 57 years. Based on the volumetric method of estimating reserves and exploration drilling data, calculations were done to determine possible depression of the seabed in the area of Shtokman gas and condensate field.
