... of this work is to estimate the "saturation pressure" of a relatively large sampling of reservoir fluids from unconventional (shale) reservoirs where these fluids tend to be near-critical volatile oils or retrograde gas condensate fluids. In this work, we utilize data from 138 PVT lab reports donated...

To maintain a high...

.... For multiphase flow in the reservoir at conditions below saturation pressure, dependence of fluid properties with pressure are handled, representing both liquid and gas fluid types. The calculations are implemented through a novel optimization algorithm after applying appropriate data pre-processing...

... and nano-scale porous media and the fluid in the nano-scale region is always leaner compared with the fluid in the macro-scale region. In addition, the saturation pressure disappears during the simulation process due to the significant differences between the macro-scale and nano-scale fluid compositions...

... to substantial amounts of oil drawdown, and that the degree of oil recovery depends on whether the reservoir is initially saturated by oil or gas, and how close conditions are to the saturation pressure (Psat). Saturation pressure is known to change most rapidly in the late oil window as volatile oils give way...
