An Assessment of Stratigraphic Sequence Interpretation from well log Data using Continuous Wavelet Transform

 abstract = {Stratigraphic interpretation is an essential task in subsurface studies. However, it is time-consuming and it often results in a small number of scenarios. Some numerical methods exist to propose automatic interpretations, based on either signal processing techniques or machine learning. These methods can be used to propose different acceptable geological scenarios from a same input log. We propose a method to assess the consistency of an automatic solution based on Continuous Wavelet Transform (CWT), with a reference interpretation. The application of this method on a Gamma Ray log highlights the potential of the CWT method for proposing stratigraphic interpretations of well logs.},
