Claim 12:
13. A method of characterizing a subterranean formation using a plurality of seismic acquisitions:
obtaining a baseline seismic acquisition of the subterranean formation, an initial completion being performed in the subterranean formation after the baseline seismic acquisition and an enhanced oil recovery operation being performed, the initial completion inducing a fracture network, the enhanced oil recovery operation including injection of a gas fluid into the subterranean formation, and the gas fluid at least partially filling a portion of the fracture network;
obtaining one or more time-dependent seismic acquisitions of the subterranean formation following a cycle in the enhanced oil recovery operation;
calculating a time-lapse difference between the baseline seismic acquisition and one of the one or more time-dependent seismic acquisitions acquired during the enhanced oil recovery operation;
determining a fluid contact parameter of the gas fluid injected during the enhanced oil recovery operation based on the time-lapse difference, the fluid contact parameter being at least one of a contact area or a contact volume; and
determining an injection conformance along a lateral of the subterranean formation based on the fluid contact parameter.
