... Chemistry WebBook, 2024 ). Polymers are more permeable to methane than to nitrogen with a relative permeability varying from 1 to over 4 ( Flaconnèche et al, 2001 ). The implication of these differences is that the energy industry has accepted that the test fluid and the operating fluid may leak...

... (Carbon Capture Utilization and Storage, CCUS) are applications based on the technical understanding of multiphase flow of gases and liquids in porous media. This paper presents the development of a sensitivity study with a 2D and 3D model to test various relative permeability functions on full-field...

... or in long horizontal cores. However, in many cases, composite cores are used experimentally, i.e. several short cores with different properties (lengths, porosities and permeabilities) are put together to form one long core during flooding. The JBN method then calculates incorrect relative permeabilities...

... Abstract The relative permeability expresses the mobility reduction factor when a fluid flows through a porous medium in presence of another fluid and appears in Darcy's law for multiphase flow. In this work, we replace Darcy's law with more general momentum equations accounting for fluid-rock...

Workflow II, in turn, accounts for the construction of a SP/SP-P under uncertainty using a robust optimization to optimize the pseudo-properties for each group of scenarios with the same relative permeability uncertainty level. The results are evaluated in terms of reduction...

...Methodology The effect of LSWF on relative permeability has been investigated using core flood experiments under the steady-state condition ( Sorop et al., 2015 ; Aljaberi et al., 2021 ). According to their findings, the kr data measured using high salinity water have been impacted because...

...Foam fluid mobility characterization In the process of foam flooding, the air foam seepage can be characterized by the Darcy seepage formula. Considering the relative permeability and apparent viscosity of the fluid, the seepage velocity is expressed: (1) v f = K K r f...

In this work, we rigorously correct the method initially presented by Gupta and Maloney (2014) to obtain accurate relative permeability data from steady-state experiments in the presence of the CEE at the end of the system. In this method, only pressure drop across the core and average water...

.... Abstract The initial water saturation in a reservoir is important for both hydrocarbon volume estimation and distribution of multi-phase flow properties such as relative permeability. Often, a practical reservoir engineering approach is to relate relative permeability to flow property regions by binning...
