Seismic Wave Excitation of Mature Oil Reservoirs for Green EOR Technology

Elastic wave-based oil mobilization of residual in heterogeneous reservoirs is a viable, low-cost, and green technology method enhanced recovery (EOR). Applications for elastic (seismic) waves at the reservoir scale are currently preliminary stages investigation development. We employ two-layer numerical finite element (FEM) this research to investigate possibility effective propagation seismic low permeability area mature when stress load delivered rock matrix via downhole source. The purpose evaluate potential fluid displacement amplitudes crossflow generation reservoir. In formation, results reveal that, as observation radius approaches boundary, time-domain performs better wave parameter than pore displacement. However, oscillations peak mesoscopic frequency 3.0 Hz produce an instantaneous transfer rate (recovery rate) 2.5% (bypassed oil) from area. This can be used combination with water flooding recover more both high low-permeability areas. Mesoscopic attenuation therefore utilized one indicators assess reservoirs.
