“…The two-dimensional sandstone slabs, in this research, were stacked as a two-layered reservoir with a glass fiber filter between the two slabs as shown in Figure 4. A glass fiber filter having mesh size of 1.6E-6 m was inserted between the slabs to obtain even contact and to provide good capillary contact (Eilertsen et al., 1996). Then, the layered system with micro fiber filter papers was thoroughly tested, so it did not form a high permeable flow path between the layers.…”

When injecting polymer into an oil reservoir, polymer adsorption onto the grain surface may seriously clog the pore throat and decrease the permeability. This phenomenon may give rise to a severe cross-flow problem in the case of a layered reservoir with a large permeability contrast. Therefore, we proposed a remedial method, which injects polymer solution with different concentrations under the same condition of the frontal velocity at each layer, to overcome the cross-flow problem. In order to perform this task, the experimental system was built as a two-dimensional two-layered sandstone system with a large permeability contrast of 10. From the results of the experimental investigation, conventional polymer flooding was found to be inefficient in oil recovery, because of the cross-flow problem that occurred almost from the beginning of injection. Meanwhile, in the case of the suggested remedial method of polymer flooding, the oil production was significantly enhanced without showing the cross-flow problem, which was accomplished by injecting the polymer solution with different concentrations under the conditions of the same frontal velocity at each layer. Overall, the suggested injecting method was found to be sufficient to overcome the cross-flow problem in a layered reservoir.

“…Its constituents are mainly silica (~90%) and alumina (~5%), with small quantities of other oxides. This material has been frequently used in previous research (e.g., Eilertsen et al 1997;Pentland 2010;Fleury 2018), given that A10 cores exhibit ranges of pore-throat size distributions, porosities and permeabilities that are comparable to those of sand packs of uniform grain sizes, with the advantage of being consolidated and reproducible. The petrophysical characteristics of A10 silicates can be consulted in the work of Hamon and Vidal (1986).…”

Analysis of the length scale characterized by the yield stress fluids porosimetry method for consolidated media: comparison with pore network models and mercury intrusion porosimetry

Substantial progress has been recently achieved in the development of a clean alternative to mercury intrusion porosimetry (MIP) based on single-phase flow measurements in porous samples using yield stress fluids. However, no study to date has examined the scale of the pore length actually provided by the yield stress fluids porosimetry method (YSM) in consolidated porous media. Indeed, while the results of YSM were compared to those provided by MIP in the past, the relationships between the characterized pore size distribution (PSD) and the actual pore geometry have still not been addressed for this type of porous media. This issue is of special interest to geoscientists involved in seeking relevant information from core characterization operations. With this aim in mind, the objective of the present paper is to evaluate the agreement between the PSDs characterized by YSM, the pore-opening size distributions provided by MIP tests, and the pore-throat and pore-body size distributions obtained from X-ray computed microtomography. For this purpose, a set of artificial and natural porous samples with permeability values extending over two magnitudes were characterized by using both YSM and MIP laboratory tests. Then, the results were matched to the model pore geometries extracted from digital images of the real microstructure. This analysis led to the main conclusion that YSM can be reliably used as an adequate substitute for MIP in the case of the investigated consolidated media, given the general agreement observed between these methods.

“…Also, the studies for the micro-and macro-scale characterization of the drainage-type displacements in the late 1990s include the development of the physically-representative network models (Bryant et al, 1996), analysis of the relationship between contact angle, corner angle, liquid saturation, and the curvature of a meniscus (Ma et al, 1996), study of the oilfloods and waterfloods in heterogeneous porous blocks (Eilertsen et al, 1997), examining meniscus intrusion into constrictions (Tsakiroglou et al, 1997), direct measurement of fluid saturation in centrifuged sample plugs (Baldwin and Spinler, 1998), capillary pressure hysteresis measurements (Hammervold et al, 1998), evaluation of the drainage-type displacement in the reservoirs which leak into overlying reservoirs (Williams, 1998), percolation theory-based analysis of the drainage (Yortsos et al, 1998), analyzing the effect of intermediate wettability on the primary drainage (Fleury et al, 1999), pore network modeling of primary drainage (Mani and Mohanty, 1999), and the evaluation of contact angle hysteresis between the drainage and the imbibition (Yang et al, 1999). Further details of these studies in the 1990s have been summarized in Table 2.…”
