Characterization of immiscible fluid displacement ...Traduire cette page

To characterize the influence of reservoir conditions upon phase flow, we calculated fluid displacements (drainage processes) in 3D pore spaces of Berea sandstone using two-phase lattice Boltzmann (LB) simulations. The results of simulations under various conditions were used to classify the resulting two-phase flow behavior into three typical fluid displacement patterns on the diagram of ...

01.09.2016 · In particular, the capillary fingering in the Berea sandstone occurs at higher Ca condition than that in the 2D homogeneous model. In addition, the saturation of the nonwetting phase (color in Fig. 3) is much different between 3D natural sandstone and the 2D homogeneous model. 3.2.

The Berea sandstone core is relatively homogeneous, whereas the Tako sandstone core is visibly heterogeneous with a coarse-grain and a fine-grain region. Rayleigh frequency has been found to have a superior performance over Brillouin frequency in terms of better consistency (less scattering) in the tests carried out. The strain gauge readings reveal considerable anisotropy in the stiffness of ...

The widely-studied Berea sandstone, from the Berea Quarry in Ohio, is an uncemented, homogeneous rock, with a narrow pore-size distribution (Bera et al., 2011). Helium porosity for a cylindri-cal core sample (2.54 cm i.d., 4 cm height) was measured by Core Laboratories Inc. (Aurora, CO) following standard procedures of API RP 40 (1960).

Internal Structures of "Homogeneous" Sandstones

Most "homogeneous" sandstones, therefore, do not represent a special sedimentary environment nor do they result from special rates of sedimentation. They develop by vertical and lateral accretion in the same manner as sediments in which stratification and other internal structures are well expressed.
