Paper Number: SPE-220728-MS
..., primarily because CO 2 can be injected more easily into macropores and mixed with the oil. Such a multiscale transport model facilitates a comprehensive understanding of the gas EOR mechanism and provides a valuable framework for designing effective EOR methods for shale reservoirs. fluid dynamics...

..., pre-combustion, and post-combustion). Reservoir flow modeling simulations show that CBFF is the best potential waterless fracturing fluid option for fracturing unconventional shale reservoirs in the Burgos Basin. We conducted fracturing simulations to obtain the fracture geometry resulting from pure...

Paper Number: SPE-205842-MS
... Abstract There are increased development activities in shale reservoirs with ultra-low permeability thanks to the advances in drilling and fracking technology. However, representative reservoir fluid samples are still difficult to acquire. The challenge leads to limited reservoir fluid data...

... ) , where T is temperature, K. As illustrated in Fig.1 and Fig.2 , water and shale gas coexist in gas shale reservoir. Shale gas stores in shale fractures/pores in free and adsorbed phases, while water initially exists in bulk and adsorbed phase in shale reservoir. The moisture content in shale...

...Conclusions The following are the significant conclusions of this study: Imbibition of low-salinity brine (e.g., fracturing fluids) into oil-wet shale reservoirs is not due to capillary imbibition or gravity—it is the result of capillary osmosis. Due to the oil-wet nature...

... by combining Gamma Log, Density Log, Neutron Log, NMR Log, and Cross-plot. An easier way to estimate porosity is provided. We combine the matrix density and kerogen density together and obtain them from core analysis. Poupon's et al. (1954) laminar model has some limitations when applying in shale reservoirs...

... with their compatibility with complex fluids at high temperature and pressure make our apparatus ideal for systematic studies of capillary condensation in shale. Abstract Shale reservoirs are estimated to account for approximately 10-30% of oil and gas worldwide, yet operators rarely produce more than 10...

Paper Number: SPE-199781-STU
... During its injection and propagation through the reservoirs, the CO 2 will have multiple interactions with the reservoir rock and fluids. These interaction will govern the ability of the CO 2 to increase oil recovery from the shale reservoir, and thus must be well understood. The interactions...

... industrial practice of fluid PVT characterization utilizes the bulk-scale PVT cell measurement. However, PVT for shale reservoirs cannot be measured in bulk-scale PVT cell because the phase behavior is significantly altered from bulk behavior by the nanopores in shale rock. In short, for shale reservoirs...
