1. A method of placing wells in a hydrocarbon field based on seismic attributes and quality indicators associated with a subterranean formation of the hydrocarbon field, the method comprising:
generating seismic data representing the subterranean formation;
receiving seismic attributes representing the subterranean formation;
receiving seismic data quality indicators;
generating cutoffs for each seismic attribute and seismic data quality indicator;
assigning a weight to each seismic attribute and seismic data quality indicator;
aggregating the weighted seismic attributes and data quality indicators for each location in the hydrocarbon field;
assigning a risk ranking based on the weighted seismic attributes and data quality indicators associated with each location in the hydrocarbon field based on the cutoffs;
generating a map with each location on a surface of the subterranean formation being color-coded based on its assigned risk ranking; and
drilling at least one location whose risk ranking is in a lowest category of risk rankings;
wherein generating cutoffs comprises performing a feasibility analysis establishing a relationship between changes of values of a seismic attribute with respect to changes of a geological property of the subterranean formation; and
wherein assigning the risk ranking based on the cutoffs comprises removing seismic data that falls outside the cutoffs.
