... immense potential for handling prominent levels of reservoir heterogeneity. The challenge of including fine-scale heterogeneity, which is often overlooked, when scaling up EOR processes from laboratory to field, appears to have found a practical solution with a combination of MS SFI and high-performance...

.... The need for new faster screening methods stems from the challenge of making robust forecasts for naturally fractured carbonate reservoirs. First order uncertainties including the distribution and properties of natural fractures, matrix heterogeneity and wettability can all negatively impact on recovery...

..., to select the optimal operational parameters for this process in heterogeneous reservoirs is non-trivial, as it involves the optimization of multiple distinct objectives including oil production, solvent recovery (efficiency), and solvent-oil ratio. Traditional optimization approaches that aggregate...

..., it leads to an improved estimate of the uncertainty in future production. We demonstrate that the validity of this assumption depends on the length of the history match period and that of the forecasting period. It also depends on how heterogeneous the reservoir is. The correlation between the quality...

... heterogeneity neighbor Indicator Introduction The modern process of characterizing and managing assets leads to creating reservoir models that are becoming increasingly large, detailed and complex. Accounting for heterogeneous structures and geologic processes on a variety of spatial scales...

... researchers disregard viscous fingering by claiming that channeling dominates at the large scale for heterogeneous reservoirs, they miss the existence of viscous fingering at the small scale, which affects the displacement efficiency. To overcome this limitation, an effective-fingering model was developed...

... Abstract We have previously introduced a transformation based upon the Fast Marching Methods (FMM) to describe the multi-dimensional diffusivity equation with heterogeneity as an effective one dimensional diffusivity equation in a streamtube. In the current study we develop and validate new...

We validated this integrated method in a synthetic heterogeneous reservoir to test its reliability and further applied it to a field case in western Venezuela. Both case studies demonstrate that this integrated model can...

... of a “ferrofluid” slug in a heterogeneous reservoir and its response to a crosswell magnetic tomography system. Specifically, we highlight the magnetic response at a low frequency (10 Hz) to the magnetic excitations generated by a vertical magnetic dipole source positioned at the injection well. The “ferrofluid...

... geometries that describe geologic heterogeneities (e.g. faults, stratigraphic, sedimentologic and/or diagenetic features) are modelled as discrete volumes bounded by surfaces, without reference to a predefined grid. These surfaces, and also well trajectories, are created and modified using intuitive...

...-scale heterogeneities into reservoir-scale models is accomplished through an effective two-stage multiphase upscaling technique. The two stages of scale-up involve (1) bed to genetic-unit scale upscaling and (2) genetic-unit to reservoir scale upscaling. In the bed to genetic-unit scale upscaling step...

Compared with black-oil models, the interactions between the thermodynamic phase behavior and the sub-grid heterogeneities that are associated with compositional displacements pose significant additional challenges to upscaling. We introduce a new framework...

In contrast, we argue that if there is an identified geological heterogeneity controlling the spatial...
