... to be linked to hydraulic fracturing operations that developed unconventional resources. The underlying triggering mechanisms of hydraulic fracturing-induced seismicity are still uncertain. The interactions of well stimulation and geology-geomechanical-hydrological features need to be investigated...

... Abstract The exploitation of shale gas has attracted extensive attention in industry and academia. Multi-scale gas transportation mechanisms in matrix and fractures have been well studied. However, due to the presence of water originating from both fracking fluids and connate water, shale gas...

... on the dissolution, wettability alteration, and mechanical properties of the carbonates in the context of modified-salinity water flooding in the North Sea chalk reservoirs. We modify a charge-distribution multi-site complexation (CD-MUSIC) model and optimize its parameters by fitting the model to a large data set...

... Abstract Nano-scale pores and a dual storage mechanism shared between free and adsorbed gas make the transport behavior in shale gas reservoirs very different from conventional macropore reservoirs. This work explores a straightforward model for the gas transport behavior in shale nanopores...

... of its importance. We investigated two key physical processes that occur during near-Miscible WAG (nMWAG) processes, namely oil stripping (Mechanism 1, M1) and low-interfacial-tension (IFT) film flow effects (Mechanism 2, M2). The low IFT effects in M2 manifest themselves in an increased mobility of oil...

... Abstract It has been amply proven through laboratory studies, affirmed by a few field trials, that dilution of brine injected has a potent impact on improving oil recovery in carbonate reservoirs. However, debate still exists as to the mechanisms responsible for such impact. The widely...

... Abstract Shale gas reservoir is comprised of highly heterogeneous porosity systems including hydraulic/secondary fractures, inorganic and organic matrix. Multiple non-Darcy flow mechanisms in the shale matrix further bring challenges for modeling. In this paper, we developed a framework...

... In addition, most of the gas tends to adsorb on the surface of organic pores, as indicated by the experiment data that the total amount of adsorbed gas has a strong linear correlation with the organic matter content ( Zhang et al., 2012 ). This adsorption phenomenon provides another mechanism...

... mechanism matrix block Introduction There is a growing concern about the rising levels of anthropogenic CO 2 in the atmosphere, because they are one of the contributors to the increase in global average temperature. During the last two decades, the identification and development of reliable...

... Currently, the previous models cannot reasonably describe all known bulk gas transport mechanisms. The Klinkenberg model is only valid for continuous flow and slip flow ( Klinkenberg 1941 ). The Javadpour model is a linear sum for slip flow and Knudsen diffusion, and the coupling between the two...

... abstract Black-oil models neglect diffusive mechanisms such as molecular diffusion or mechanical dispersion; this omission produces a propensity to developing shocks. This paper aims to carry out an exhaustive identification of the kind of shocks that can occur when black-oil models are applied...
