What is it about?
To improve the development efficiency of mature oil fields, unsteady-state (cyclic) waterflooding offers an alternative to tertiary enhanced oil recovery methods. The novelty of this study lies in the laboratory studies of the hysteresis of relative phase permeabilities (HRPP) in water-oil systems, which are then used to evaluate the effectiveness of cyclic waterflooding technology using an updated 3D hydrodynamic model using tNavigator software. The importance of incorporating models with inverse hysteresis loops into commercial simulators for carbonate porous media with mixed wettability is demonstrated and justified, and avenues for future research are proposed.

Why is it important?
The importance of incorporating models with inverse hysteresis loops into commercial simulators for carbonate porous media with mixed types of rock wettability is demonstrated and justified, and directions for future research are proposed
Perspectives
These findings emphasize the need for laboratory studies of carbonate reservoirs in imbibition and drainage modes to constrain the real reservoir processes occurring during cyclic waterflooding.
