The stress sensitivity of permeability in tight oil reservoirs [PDF]
Energy Exploration & Exploitation, 2019 In the development of tight reservoirs, the permeability of the rock possesses strong stress sensitivity with the dynamic change of formation pressure and effective stress. To quantify the stress sensitivity of permeability in tight reservoirs and its impacts on the oil production, we carried out a systematic experimental study using core samples from ...

On the Imbibition Model for Oil-Water Replacement of Tight Sandstone Oil Reservoirs [PDF]
Geofluids, 2021 A model suitable for evaluating a tight sandstone reservoir is established. The model includes two oil-water replacement modes: capillary force mode and osmotic pressure mode. The relationship between oil-water displacement rate and dimensionless time under different parameters is drawn considering the influence of capillary force, osmotic pressure ...

Mechanism of Permeability and Oil Recovery during Fracturing in Tight Oil Reservoirs [PDF]
Processes, 2020 In this study, the effect of fracturing fluid on the permeability of tight oil reservoirs is analyzed through oil absorption. The mechanism of permeation and absorption in tight oil reservoirs was studied using the molecular dynamics simulation of fluid flow through fractures in porous media containing crude oil.
