Gas-water relative permeability of unconventional reservoir rocks: Hysteresis and influence on production after shut-in

Journal of Natural Gas Science and Engineering, 2020
Relative permeability is one of the most important parameters in reservoir modeling. However, measurements of relative permeability in unconventional reservoir rocks are rare, and the influence of relative permeability hysteresis on reservoir studies has

Non-uniqueness and uncertainty quantification of relative permeability measurements by inverse modelling

, 2021
Relative permeability is traditionally obtained in core flooding experiments from production data and pressure drop either using analytical methods or inverse modelling.

A new approach to measure wettability by relative permeability measurements

Journal of Petroleum Science and Engineering, 2021
Wettability is a key factor controlling the flow of fluids, solutes, heat and electrical current in porous media, and therefore it is important in studies of various processes including CO2 storage, secondary and tertiary oil recovery, as well as the ...

Relative Permeability Hysteresis and Capillary Trapping during CO2 EOR and Sequestration

, 2021
Residual or capillary trapping is an important mechanism of CO2 trapping in underground porous media. Recent experimental investigation has shown that relative permeability and capillary pressure are function of saturation changing direction or ...

Accelerated Computation of Relative Permeability by Coupled Morphological and Direct Multiphase Flow Simulation

Journal of Computational Physics, 2020
Computation of two-phase flow in porous media with low capillary numbers is challenging due to slow convergence and the presence of spurious currents at the phase interfaces that are greater than the viscous flow.

New methods for qualitative and quantitative determination of wettability from relative permeability curves: Revisiting Craig’s rules of thumb and introducing Lak wettability index

, 2020
Craig’s rules of thumb have been widely used for qualitative determination of wettability from relative permeability curves. According to the first rule, in water-wet rocks the water relative permeability at residual oil saturation (ROS) is generally ...

A fractal model for gas-water relative permeability curve in shale rocks

Journal of Natural Gas Science and Engineering, 2020
Initial water content and subsequent fracturing fluid injection lead to gas-water flow in shale nanopores, especially the water-wet pores. But there is few research and experiment to introduce relative permeability curves governing multiphase transport ...

Relative Permeability from Capillary Pressure

SPE Annual Technical Conference and Exhibition, 2002
Abstract A new theory is reviewed for single-component, two-phase flow in porous media. It includes wettability and capillary pressure as integral parts of the thermodynamic description and does not make use of the relative permeability concept.

Effect of fines migration and mineral reactions on CO2-water drainage relative permeability

, 2020
CO2-water drainage relative permeability is usually measured in laboratory using a three-stage unsteady-state flooding on cores. This three-stage flooding involves injecting water, then CO2-saturated water, and finally water-saturated supercritical CO2 ...
