Optimization of Lattice Boltzmann Simulation With Graphics-Processing-Unit Parallel Computing and the Application in Reservoir Characterization

Abstract: Shale permeability is sufficiently low to require an unconventional scale of stimulation treatments, such as very-large-volume, high-rate, multistage hydraulic-fracturing applications. Upscaling of hydrocarbon transport processes in shales is challenging because of the low permeability and strong heterogeneity. Rock characterization with high-resolution imaging [X-ray tomography and scanning electron microscope (SEM)] is usually highly localized and contains significant uncertainties because of the small field… Show more

“…During the LB simulation, we monitored the relative change of simulated permeability with respect to the previous time step; the simulation terminated when the relative change was below the specified criterion of 0.1% (Chen et al, 2008, 2009, 2016). For each 3D tomographic image in this research, the total number of grids was as high as 64,000,000, which makes the LB simulations computationally expensive.…”

“…The method characterizes the physics of the macroscopic behavior by tracking the local mesoscopic behavior, such as the motion and collision of particles on a regular grid. The local nature of the LBM makes it appropriate for parallel computing (Chen et al, 2016). In addition, the bounce‐back scheme (non‐slip condition) of the LBM allows boundary conditions with complex geometries to be implemented easily (Chen et al, 1992).…”
