Shales are becoming the most important source of natural gas in North America, and replacement coal by is reducing CO2 emissions improving air quality. Nevertheless, shale facing strong opposition from environmental nongovernmental organizations. Although these organizations have greatly exaggerated potential negative impacts oil, methane leakage contamination groundwater surface water flowback produced waters serious concerns. These pathways not unique to they manageable.
Abstract Type I kerogen was isolated from Green River Shale and characterized using SEM, TGA, DSC, nitrogen adsorption. The swelling behavior of this with decane analyzed traditional test-tube experiment Dynamic Light Scattering. TGA DSC were used to analyze the thermodynamic that sorbed in show suppresses boiling point due effect confinement. However, suppression is larger when oil (a multicomponent mixture) used, possibly combined differential uptake components by (kerogen prefers sorbs...
Abstract Understanding mechanisms controlling fluid injection-triggered seismicity is key in defining strategies to ameliorate it. Recent triggered events (e.g. Pohang, Mw 5.5) have exceeded predictions of average energy release by a factor >1000x, necessitating robust methodologies both define critical antecedent conditions and thereby constrain anticipated event size. We maximum magnitudes resulting from triggering as function pre-existing stresses injection volume. Fluid experiments on...
In molecular dynamics simulations, a combination of short-range repulsive and long-range attractive interactions allows the behavior gases, liquids, solids, multiphase systems to be simulated. We demonstrate that dissipative particle (DPD) simulations with similar pairwise particle-particle can also used simulate fluids. these positive, short-range, part interaction potentials were represented by polynomial spline functions such as those smoothing in smoothed hydrodynamics, negative has same...
Complex fluid behavior in unsaturated fracture and networks, such as film flow, the migration, fragmentation, coalescence of droplets, rivulet flow with or without meandering pulsation, has been widely observed laboratory experiments. In this study, a modified two‐dimensional volume (VOF) method was used to simulate liquid motion partially saturated apertures under variety conditions. This modeling approach systematically incorporates effects inertial forces, viscosity, gravity acting on...
A pore‐scale simulation technique based on level set interface tracking has been developed for modeling coupled reactive flow and structure evolution in porous media fracture apertures. Advection, diffusion, mineral precipitation resulting changes pore geometries are treated simultaneously by solving fully fluid solute transport equations. The reaction‐induced of solid grain surfaces is captured using a method, subgrid representation the approach used instead pixel often cellular automata...
Multiphase fluid motion in microchannels and microchannel networks involves complicated dynamics is fundamentally important to diverse practical engineering applications such as ink-jet printing, DNA protein micro-/nano-arraying, fabrication of particles capsules for controlled release medicines. This paper presented the simulations multiphase using a modified dissipative particle method that employs new conservative particle-particle interaction combining short-range repulsive long-range...
A many-body dissipative particle dynamics model, namely, MDPD, is applied for simulation of pore-scale, multi-component, multi-phase fluid flows in fine-grained, nanoporous shales. Since this model able to simultaneously capture the discrete features molecules nanometer size pores and continuum larger pores, relatively easy parameterize, it has been recognized as being particularly suitable simulating complex flow multi-length-scale nanopore networks remarkable feature work integration a...
Multiphase fluid flow through porous media involves complex dynamics, and it is difficult to model such behavior, on the pore scale, using grid‐based continuum models. In this paper, application of dissipative particle dynamics (DPD), a relatively new mesoscale method, simulation pore‐scale multiphase flows under variety conditions described. We demonstrate that conventional DPD method purely repulsive conservative (nondissipative) particle‐particle interactions capable modeling single‐phase...
Inverse estimations of hydrogeologic properties often are highly uncertain because the expense collecting data and subsequent lack information. Geophysical potentially can help fill this information gap geophysical methods survey large areas remotely relatively inexpensively. However, difficult to incorporate into parameter primarily a knowledge concerning petrophysical relationships between parameters. A method be used that allows time-lapse incorporated directly estimation when strong...
Molecular dynamics simulations were performed with a ReaxFF reactive force field to investigate bond breaking and formation mechanisms during the thermal maturation of three kerogens potential cross-linking pathways toward three-dimensional (3D) quasi-infinite molecular networks (cross-linked kerogen macromolecules). Starting small ensembles high mass models for immature type I Green River Shale (kerogen 1-I), top oil window II 2-L), low maturity III 3-L), species including H2O, C2H4, C3H6...
Rocks are host to complex fracture networks that difficult locate in situ, and yet characterization of these fractures is crucial predicting the effects hydraulic stimulation. We analyze three-dimensional patterns among varied laboratory experiments identify recurring geometries. Building on constitutive tensile shear modes, we observe examples offset branching, traversing coalescence, smooth reorientation as relatively simple structures within networks. The evolution also referred...
Abstract Recent technological advances like horizontal drilling and hydraulic fracturing have made recovery of gas possible from the ultra low permeable shale plays in United States. However, recoveries these shales still tend to be range single digits. It is believed that more than 80% generated hydrocarbons remain tight formations. In order increase plays, an enhanced procedure using supercritical carbon dioxide as injection fluid recommended this paper. current research, molecular...
