1. A method for stimulating a reservoir, the method comprising:
providing a well traversing a subsurface into a reservoir containing hydrocarbons;
introducing carbon dioxide and steam into the reservoir via the well;
stimulating the reservoir using one or more of infrasonic, acoustic, and ultrasonic stimulation;
applying seismic analyses to determine changes in flow characteristics of the reservoir in response to introducing carbon dioxide and steam, and stimulating the reservoir;
monitoring a flow back effluent via one or more sensors located in the well to determine one or more properties of the flow back effluent; and
repeating introducing carbon dioxide and steam, stimulating, and applying seismic until a desired property of the flow back effluent is achieved.
