... the bubble point pressure is close to the initial reservoir pressure, optimal bottomhole pressures differ significantly from limiting bottomhole pressures and, thus, should be calculated. In case the bubble point pressure is lower than the original in-situ pressure, limiting bottomhole pressure is the right...

...) and why it is caused. For example, (Zapivalov, 2003) 12 explains the convexity of the PC to the axis of production by closing the cracks, when still the bottomhole pressure does not drop below the bubble point pressure. This phenomenon occurs both in limestones and in terrigenous ones, in which...

... of the behavior of black oil. Basic parameters of PVT model correlation are R sb - gas-oil ratio at bubble point, γ o - oil specific density, γ g - gas specific density, P b - bubble point pressure, T res - reservoir temperature. It should be noted these parameters can be obtained in different...
