Sammendrag
This thesis considers an approach to tackle a core problem within seismic interpretation, which is bringing an autonomously generated interpretation of the seismicdata, which is now known as a Relative Geologic Time. The proposed method readily utilizes the method of Dynamic Time Warping, which is an established methodwithin signal processing. Using Dynamic Time Warping is thought to replicate similar interpretations an interpreter would conduct when fulfilling an interpretation ofthe subsurface. Utilizing Dynamic Time Warping to seismic data results in a fullyautonomous interpretation of the subsurface, conducted in minutes and seconds. Themethod is simple and extendable, which can easily be further expanded. The workflow established during the thesis work results in a method that successfully producesan RGT volume. However, problems related to the method must be improved toenhance the outcome further and diminish errors present in the result. Furthermore,even with problems associated with the method, potential solutions are described indetail in the discussion and appendix. Discussion affiliated with previous attemptsin solving Relative Geologic Time volumes is emphasized. The research conducted inDynamic Time Warping is promising and emits potential for further research. LaTeXsetup by Gunn and Patel (2017).
