- Automatic seismic event tracking using a dynamic time warping algorithm
In this paper, we develop an automatic seismic event tracking method of horizon interpretation using the dynamic time warping (DTW) algorithm The proposed method consists of two steps: calculating local time shifts between adjacent traces through a pilot trace and then event tracking
- Dynamic Time Warping as an Alternative to Windowed Cross Correlation in . . .
We investigate the feasibility of using the dynamic time warping (DTW) technique as an alternative to windowed cross correlation (WCC) for an indirect measure to quantify both the similarity and relationship between two seismic time series
- Seismic data extrapolation based on multi-scale dynamic time warping
A new workflow for seismic data extrapolation is proposed to address this issue, which is based on a multi-scale dynamic time warping (MS-DTW) algorithm MS-DTW can accurately calculate the time-shift between two time series and is a robust method for predicting time-offset ( t − x ) domain data
- Dynamic warping of seismic images - GEOPHYSICS
By applying the same nonlinear accumulator repeatedly in all directions along all sampled axes of a multidimensional image, I obtain a new and effective method for dynamic image warping (DIW) In tests where known shifts vary rapidly, this new method is more accurate than methods based on crosscorrelations of windowed images
- A Dynamic Time Warping Loss-Based Closed-Loop CNN for Seismic Impedance . . .
In order to tackle the problem, we propose a dynamic time warping (DTW) loss-based closed-loop convolutional neural network (CNN) for seismic impedance inversion First, DTW loss and cycle-consistency loss together constrain the closed-loop CNN training to optimize the weights of neural network
- Tianci Cui and Gary F. Margrave - CREWES
Cui and Margrave (2014a) use a technique called dynamic time warping (DTW) to estimate the drift time between a stationary synthetic seismogram calculated from well logs and a nonstationary seismic trace caused by anelastic attenuation at the well location
- Automated Seismic-to-Well Ties using Dynamic Time Warping approaches
Dynamic Time Warping (DTW) is a method of aligning two signals via warping one signal to match the other and is almost instantaeous Various authors have already shown the possibilities and value of using DTW in the seismic-to-well tie process
- Seismic-well tie using fuzzy properties of acoustic . . . - Springer
This research introduces a method for seismic-well tie using a modified Dynamic Time Warping, DTW algorithm with fuzzy features The Seismic-Fuzzy DTW technique aligns synthetic seismograms to seismic traces by considering waveform similarity and geological features
