Multipoint flux approximation (MPFA) techniques are commonly applied for discretizing the porous media flow equations within the context of finite volume numerical procedures. Although these methods can be applied to heterogeneous, anisotropic systems on generally unstructured grids, the inverse of the resulting linear operator can suffer from a loss of monotonicity at high permeability anisotr...

Computational modelling of processes at pore-scale allows to get detailed insight into their nature. It also provides tools to improve coarse-scale models in which porous medium is considered as a permeable continuum. In this paper, we use the simulations at microscale combined with an upscaling procedure and describe the impact of small changes in the pore morphology on the macroscale paramete...

Reservoir simulation to predict production performance requires two steps: one is history-matching, and the other is uncertainty quantification in forecasting. In the process of history-matching, rock relative permeability curves are often altered to reproduce production data. However, guidelines for changing the shape of the curves have not been clearly established. The aim of this paper is to...

In this paper we align business with IT in a networked setting while introducing innovative e-customs procedures worldwide. We perform the alignment process in a multi-perspective way, guided by concerns of upscaling. As we show in this paper, using an industry-strength case study, effects of upscaling have often impacts on business, like the increase of the number of service consumers, or the ...

In many reservoir studies, anisotropic permeability values in orthogonal directions are often considered to have simple relationships. Often, this permeability anisotropy is modeled only between the vertical and horizontal directions as a certain ratio of values, while permeability values in a horizontal plane are considered equal. In reality, the depositional history of the reservoir results i...

Spontaneous imbibition has been receiving much attention due to its significance in many subsurface and industrial applications. Unveiling pore-scale wetting dynamics, particularly upscaling the Darcy scale are still unresolved. In this work, we conduct image-based pore-network modeling of cocurrent spontaneous corresponding quasi-static imbibition, homogeneous sintered glass beads as well hete...

The micropore structure’s permeability contribution to total of the heterogeneous reservoir with multiscale pore structures is critical for evaluation but still not well understood. This paper proposes a structure characterization method based on high-resolution SEM images quantitatively analyse structures’ content and their contributions via six steps. First, image-based rock typing implemente...

AEiSTRACT Reinjection of spent geothermal brine is a common means of disposing of geothermal effluents and maintaining reservoir pressures. Contrary to the predictions of twefluid models (tweviscosity) of nonisothermal injection, an increase of injectivity, with continued injection, is often observed. Injectivity enhancement and thermally-affected pressure transients are particularly apparent i...
