..., and consequently affects water-oil two-phase flow during production. Because of the complicated surface properties of the pore systems, unclear connectivity of pore networks with different wetting properties, and the small pores and low porosity, an understanding of water-oil displacement in shale and its...

.... Specifically, the properties of an organic pore network are compared over different reconstruction algorithms. First, Fourier techniques (Weighted Back-Projection, Filtered Back-Projection) and iterative techniques (Conjugate Gradient Least Squares, Simultaneous Iterative Reconstruction Technique) are used...

... utilizations of integrated FIB-SEM and STEM for high-resolution imaging of the shale organic matter and the structurally associated mineral fabric. Visualization of connected pore networks and interfaces will help to better understand the contribution of the nanoscale to the overall transport and storage...

... the interplay of fluid confinement factors on effective gas flow behaviors in shale, in this work we developed a new phase equilibrium calculation algorithm for evaluating phase properties in pores of variable sizes and a shale-gas pore-network model. We coupled them into a workflow to study the effect of shale...

... intrusion (HPMI) and low-pressure nitrogen sorption. We determined the properties of the pore network (size distribution, connectivity, spatial correlation) by constructing representative pore networks that allowed reconstruction of the HPMI and nitrogen sorption data. We then upscaled the results...

Some of these methods are generally applied to non-localized crushed powder samples, which is inappropriate for evaluating preserved...

... Abstract New imaging techniques have revealed that the pore networks of shale plays consist primarily of inorganic materials, organic matter and natural fractures. However, the flow mechanism through these multi-porosity systems is not well understood. In addition, liquid-rich shale (LRS...

... was implemented for an ideal porous material with a uniform pore size. In this study we combine the pore network with LDFT theory to study the effects of pore size, shape, connectivity and surface chemistry heterogeneity on nitrogen adsorption and desorption isotherms. A multi-scale network model is modified...

... in number, size (from nanopores to micropores), and kind (organic pores and nonorganic pores). Thus far, the role of pore network and, more specifically, what pores contribute the most to the hydrocarbons storage or the production process, is not well understood and remains largely unknown. Hence...

... Abstract We create two-dimensional (2D) and three-dimensional (3D) physical representations of shale pore networks using cleanroom nanofabrication methods and agarose polymer and experimentally investigate two-phase fluid transport in these nanoscale domains. A key question uniquely addressed...

... and their impact on fluid flow in these rocks is poorly understood. The unconventional rocks, such as shale rocks, are highly heterogeneous, fine-grained, and their representative elementary volume is uncertain. In order to identify flow pathways in the pore network of these rocks, it is essential to characterize...

If it is mixed wet but hydrophobic, then forced imbibition is required to get the water...
