文摘In most literatures reservoir engineers usually claimed that oilfields are not identical to each other.To the author's experience on the type-curve matching work as mentioned above,it is not uncommon to find two fields exhibiting almost identical performances throughout their whole production life.In Fig.1,oil and water production figures of two well-known giant oilfields of former USSR-Romashkino(A)and Samotrol(B)are plo-tted together as Type-A curves with software“TWDTC".Surprisingly,nearly all the data points which covered 18-24 years of production history for both fields fell almost on one straight line.This implies that these two fields should have the same magnitude of active OOIP and in the same time,exercise similar waterflooding performance during their whole produciton life.
