Dynamic phase permeability for calculating oil locations in digital models
Известия высших учебных заведений: Нефть и газ, 2021 The article presents the author's formulas for calculating the residual oil saturation and the end points of relative phase permeabilities that dynamically depend on the filtration rate of reservoir fluids and capillary numbers.

The research on the classification method of high water-cut well group in Y block [PDF]
E3S Web of Conferences, 2020 Y block has entered the ultra-high water cut stage of production, and the water cut of oil wells is generally higher than 90%. Before polymer flooding, water cut continues to rise.

Experimental Investigation of the Effect of Polymers on Residual Oil Saturation [PDF]
SPE Improved Oil Recovery Conference, 2016 Abstract Polymer flooding is a widely used commercial process with a low cost per barrel of produced oil, For this application, hydrolyzed polyacrylamide (HPAM) polymers are the most widely used type of polymer. In an era of low cost oil, it is becoming even more essential to optimize the polymer flooding design under realistic reservoir

State-of-the-art report summarizing techniques to determine residual oil saturation and recommendations on the requirements for residual oil saturation research and development [PDF]
, 1986 An investigation was conducted on the residual oil saturation (ROS) measurement techniques developed during the last fifteen years. Knowledge of precise ROS measurements is required for EOR project planning. The advantages, limitations, and problems of each one of the techniques are presented in tabulated form.
