Accurate well-tying and wavelet estimation is a critical step in reservoir characterization. Jason WellTie provides a highly visual and interactive environment for creating, refining and QC'ing wavelets for inversions.
With a proper wavelet, the user can be confident in the results of:
The well tie process utilizes two key Jason applications that work together: Estimate Wavelets and Well Log Editor. The optimum wavelet is determined to be that which, when convolved with well log reflectivities, results in a synthetic that best matches the input seismic in a least-squares way. The candidate wavelet is further vetted by evaluating its ability to perform seismic inversion on the input traces. Various QCs are available to evaluate its performance.
Key features of the process include:
Jason WellTie supports a variety of wavelet estimation strategies:
QC tests are available throughout the wavelet estimation and well tie processes.
Among the many quality control panels are:
These panels provide a visual cue to problems with the wavelet and data that can be used to correct them. The combination of a streamlined process, inversion-based estimation, true multi-well handling and frequent QC steps gives Jason WellTie users a straightforward and reliable method of identifying the best fit wavelet for their data.
Compute all your AVO wavelets for inversion simultaneously. In addition apply spectral amplitude and phase constraints between wavelets in adjacent partial offset or angle stacks.
Use the new Jason workflow to compute wavelets from broadband data to achieve broadband inversions. Leverage the advantages of broadband for even greater resolution in reservoir characterization.
