Authors: S.V. Mikhajlova, Yu.V. Filippovich (Gazpromneft NTC LLC)
The method to forecast the overpressure in inversion structures is described. On the basis of inversion modeling the forecast reservoir pressure values were estimated, the overpressure ratio map was made. The increase of oil flow in wells with an increase of overpressure ratio is noticed. The forecasting of high oil flows in zones of high values of overpressure ratio was proved by drilling in 2011.
