1. A method for predicting a risk during drilling operations of a well, which comprises: a) defining a coarse layer model and a fine layer model for each layer of the coarse layer model based on a model type for the well comprising at least one from fuzzy mapping and static mapping; b) training the coarse layer model and each fine layer model using a computer processor, the model type and at least one of segmented historical data and one or more extracted features representing each respective historical data segment; c) repeating steps a)-b) with another model type until the coarse layer model and each fine layer model are acceptable; d) predicting the predetermined risk for the well using an acceptable coarse layer model, each acceptable fine layer model and real-time data for the well received during drilling operations; and e) adjusting at least one of the drilling operations based on the predetermined risk predicted for the well.
