Claim 0:
1. A method of characterizing a subterranean formation:
obtaining a first seismic acquisition of the subterranean formation, wherein the first seismic acquisition is a baseline survey, an initial completion being performed in the subterranean formation after the first 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 a plurality of second seismic acquisitions of the subterranean formation during the enhanced oil recovery operation, wherein each of the plurality of second seismic acquisitions is respectively captured following a cycle in the enhanced oil recovery operation;
calculating a time-lapse difference between the first seismic acquisition and one of the plurality of second seismic acquisitions;
determining a fluid contact parameter of the gas fluid injected during the enhanced oil recovery operation based on the time-lapse difference between the first seismic acquisition and the one of the plurality of second seismic acquisitions acquired during the enhanced oil recovery operation, 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.
