WebJan 19, 2024 · The three primary oil reservoir drive mechanisms are solution gas drive, gas cap drive, and water drive. [1] Reservoir pressure trends and producing gas-oil ratio trends of these three drive mechanisms are shown in Figures 1 and 2, respectively. A combination or mixed drive occurs when two or more of the primary drive mechanisms are present in ...

Webhydrodynamic forces such as flow from a remote aquifer, and interfacial forces that act between the various reservoir fluids and between the fluids and the rock matrix. The interfacial forces either take the form of (i) forces on the interface between two fluids, or (ii) between the fluid and the solid matrix of the rock. WebMar 1, 2015 · Each hydraulic flow unit is represented by a flow zone indicator (FZI) (Abbaszadeh et al., 1996). The points with similar FZI are placed in the same flow unit. FZI, which is in fact the factor determining the flow units, do not necessary depend on facies and different facies can be located in a single hydraulic flow unit.
