Petrophysical initialization of core-scale reactive transport simulations on Indiana limestones: Pore-scale characterization, spatial autocorrelations, and representative elementary volume analysis

نویسندگان

چکیده

Initializations of the petrophysical parameters significantly affect results reactive transport simulations on unstable dissolution fronts. As phenomenon arises from inherent heterogeneity rocks, heterogenous initialization fields is needed to model such a phenomenon. While modeling fronts has been extensively studied in past, geostatistical information required initialize heterogeneous usually assumed and still missing. The objective this paper acquire for Indiana limestones core-scale. This done by combining high resolution tomography with pore scale calculations determine: i) rock minimum representative volume (REV), ii) frequency distributions parameters, namely; porosity, permeability, surface area, iii) relationships between iv) spatial correlation lengths. obtained should help reduce uncertainties associated core-scale carbonate rocks general, particular.

Pore-scale Characterization of Carbonate Rock Heterogeneity and Prediction of Petrophysical Properties

Carbonate reservoirs, accounting for majority of the world’s hydrocarbon reserves, are well known for their heterogeneity and multiscale pore characteristics. The pore sizes in carbonate rock can vary over orders of magnitudes, the geometry and topology parameters of pores at different scales have a great impact on flow properties. A relatively simple way to integrate a set of digital pore spac...

Continuum-scale characterization of solute transport based on pore-scale velocity distributions

We present a methodology to characterize a continuum-scale model of transport in porousmedia on the basis of pore-scale distributions of velocities computed in three-dimensional pore-space images. The methodology is tested against pore-scale simulations of flow and transport for a bead pack and a sandstone sample. We employ a double-continuum approach to describe transport inmobile and immobile...

Petrophysical analysis of regional-scale thermal properties for improved simulations of geothermal installations and basin-scale heat and fluid flow

The development of geothermal energy and basin-scale simulations of fluid and heat flow both suffer from uncertain physical rock properties at depth. For the production of geothermal energy, a high risk of failure is associated with this uncertainty. Invoking the usual conservative assumptions as a remedy results in unnecessarily large drilling depths and increased exploration costs. Therefore,...

On pore-scale modeling and simulation of reactive transport in 3D geometries

Pore–scale modeling and simulation of reactive flow in porous media has a range of diverse applications, and poses a number of research challenges. It is known that the morphology of a porous medium has significant influence on the local flow rate, which can have a substantial impact on the rate of chemical reactions. While there are a large number of papers and software tools dedicated to simu...

Multiblock Pore-Scale Modeling and Upscaling of Reactive Transport: Application to Carbon Sequestration

In order to safely store CO2 in depleted reservoirs and deep saline aquifers, a better understanding of the storage mechanisms of CO2 is needed. Reaction of CO2 with minerals to form precipitate in the subsurface helps to securely store CO2 over geologic time periods, but a concern is the formation of localized channels through which CO2 could travel at large, localized rates. Pore-scale networ...
