Volume 4, Issue 4 , Autumn 2015, , Pages 1-14


  Seismic waves are non-stationary due to its propagation through the earth. Time-frequency transforms are suitable tools for analyzing non-stationary seismic signals. Spectral decomposition can reveal the non-stationary characteristics which cannot be easily observed in the time or frequency representation ...  Read More

2. An Improvement in Temporal Resolution of Seismic Data Using Logarithmic Time-frequency Transform Method

Amin Roshandel Kahoo; Saman Gholtashi

Volume 4, Issue 2 , Spring 2015, , Pages 27-39


  The improvement in the temporal resolution of seismic data is a critical issue in hydrocarbon exploration. It is important for obtaining more detailed structural and stratigraphic information. Many methods have been introduced to improve the vertical resolution of reflection seismic data. Each method ...  Read More
