... Abstract Laboratory-based petrophysical measurements, including saturation-dependent relative permeability measurements, play a critical role in evaluating the fluid-flow characteristics in organic-rich mudrocks. However, acquiring a perfectly-shaped cylindrical core sample in these organic...

... Abstract Understanding the fluid-flow characteristics in reservoir rocks requires a reliable assessment of permeability and saturation-dependent relative permeability. It is also essential for quantifying the primary recovery mechanisms and enhancing the ability to exploit reserves...

... Abstract Fluid flow in the pore network depends on the preferential movement of different fluid phases. To understand the preferential movement of different fluids in the reservoir, saturation-dependent petrophysical properties such as relative permeability are critical. Therefore, saturating...

... and fractures network scale. This work presents an empirical correlation for water-hydrocarbon relative permeability prediction in fractured reservoirs, as a function of stress state and capillary number variations usually relevant in the stimulated reservoir volume – SRV after hydraulic fracturing...

... the Woodford well. Fluid content and composition vary across the identified faults. In both wells, the rock near the faults is hydrophobic and has a poor relative permeability for oil. Changes in CO 2 content between both sides of the faults suggest variability in reservoir pressure in both reservoirs...

... Abstract Water-oil (W-O) relative permeability is a critical parameter in modeling practices for performance prediction and water management of unconventional reservoirs. To date, laboratory measurements of W-O relative permeability have been limited to conventional rocks with permeability...

... Abstract Relative permeability is one of the most critical parameters for reservoir modeling. However, reliable measurements of relative permeability are lacking, and the influence of relative permeability hysteresis has not yet been addressed for unconventional reservoir rocks. This paper...

... by the interplay between the competing opposite effects of drawdown, compressibility and relative permeability. Transient IPRs are not based on average reservoir pressure, but on specified times. In fact, we propose a triple combo IPR consisting of a set of 3 flow durations (e.g. 30-, 90- and 180-days, or 1-, 3...

... Abstract Relative permeability is a significant source of uncertainty in current modeling practices for performance prediction of unconventional reservoirs. Due to the lack of reliable measurements or representative analogs, relative permeability is often used as an unconstrained history...

... Abstract Relative permeability has a significant impact on gas or oil and water production, but is one of the most complicated properties in unconventional reservoirs. Current understanding on relative permeability for unconventional reservoir rocks is very limited, mainly because of a lack...
