Abstract：Thin interbed thickness prediction is one of the most difficult problems in petroleum exploration. We use the Teager-Kaiser energy associated with wavelet transform to generate a joint time-frequency representation, which is constructive to detect thin beds. Then we calculate peak instantaneous frequency in a small window around thin bed response. Thin interbed thickness can be predicted by the relation between peak instantaneous frequency and thickness of wells which located in the area. Model and real data examples indicate that the method can well predict thin interbed thickness. The peak instantaneous frequency has a close relationship with the layer thickness measured on logging data, and predicted thin interbed thickness matches very well with its thickness on logging isopach maps.
