Here we examine the consequences of uncertainty with respect to geological parameters, using large-scale 2D models. We also investigate ways to reduce prediction uncertainty, either by showing how a parameter’s influence is negligible for a given project design, or by showing for which parameters additional data will significantly increase the quality of prediction. TOUGH2/ECO2N is used to simu...

In random network models, sizes for pores and throats are distributed according to a truncated Weibull distribution. As result, parameters defining the shape of distribution critical characteristic network. this paper, an algorithm distribute in was established more representatively describe topology porous media. First, relations between dimensionless throat were studied series standard curves...

Carbonate reservoirs rock typing plays a pivotal role in the construction of reservoir static models and volumetric calculations. The procedure for rock type determination starts with the determination of depositional and diagenetic rock types through petrographic studies of the thin sections prepared from core plugs and cuttings. In the second step of rock typing study, electrofacies are deter...

Wettability is a pore-scale property that impacts the relative movement and distribution of fluids in porous medium. There are reservoir provoke surface within pores to undergo wettability change. This change, turn, alters dynamics permeabilities at Darcy scale. Thus, modeling impact change essential understand interaction media. In this study, we include time-dependent into permeability–satura...

Wettability characterization of a porous material has been mainly addressed so far in terms an average contact angle. Here, methodology is proposed to determine the angle spatial distribution medium statistical sense and hydrophilic pore fraction, assuming take binary values. This achieved by means minimization procedure on relative permeability capillary pressure curves with inverse method bas...

Fluid transport through reservoir recks is complex and cannot be described by theory alone. Darcy’s law, an empirical equaiion describing the Iami”ar flow of incompressible fluids, is largely used for calculation of fluid flow through porous media. It relates the macroscopic veloci~ (flux) of a fluid of known viscosity to the pressure gradient by a pmpotiionalky factor called absolute permeabil...

This paper addresses two issues. Firstly, because the coarse­scale model inevitably misses out sub­grid heterogeneity, physical dispersion is ignored in the simulation. Secondly, the small­scale heterogeneity is not explicitly known and can only be inferred by history­matching. To solve these problems, local features in the coarse­scale relative permeability curves were adjusted in history­matc...
