oa Lattice Boltzmann Simulation for Flux Change Under Oscillating Boundary Condition

Seismic stimulation is known as one of the methods of Enhanced Oil Recovery (EOR). Numerous observations show that seismic stimulation of oil reservoir may alter water and oil production. Recent studies attempted to show detailed mechanisms of seismic stimulation. But understanding the detail mechanisms, it is necessary to delineate the relationship between macroscopic and microscopic phenomena So, to use seismic EOR efficiently, we attempt to understand amplitude characteristics and frequency characteristics of the flux change in viscous laminar flow under oscillating boundary condition to simulate seismic EOR. In this time, we start to analyze a single-phase flow in various pore shapes and scales with 2D LBM scheme. The results show seismic amplitude, frequency, pore scales, shapes and angle are largely related with the flux change, because of the reduction of pressure loss and the flow velocity difference between the wall and flow.
