| | Abstract | | The amount of oil production in the world is decreasing recently and it is important to seek the technological development for enhanced oil recovery in place in the subsurface. Seismic stimulation is known as one of the methods of EOR. Recently, many laboratory experiments and field tests have been performed such as water, gas, chemical, or thermal injections to attempt the enhancement of oil production. Numerous observations show that seismic stimulation of oil reservoir may alter water and oil production. But the detailed mechanism of seismic stimulation is not fully understood. We attempt to understand the mechanism of the flux change in viscous laminar flow under oscillating boundary condition to simulate seismic EOR. We start to analyze a single-phase flow in a pore throat with 2D FEM scheme. The results show the possibility of flux increment by the oscillated boundary wall because of partial high pressure gradient and flow velocity difference between the wall and flow. |
