WebABSTRACT Seismic–well tying is an important technique for correlating well-logging curves in depth with seismic traces in time. An appropriate seismic–well tying technique must account for two types of nonstationarity: the nonstationary time errors in the synthetic seismic trace caused by the inaccurate time–depth relationship established based on … WebMay 12, 2015 · Average all the wavelets you got and tie all your wells with this wavelet. The ties should improve in most cases. Note: Step 4 usually involves estimating the wavelet from the seismic data, using the reflectivity from the wells. It's basically the reverse of making a synthetic: seismic / reflectivity = wavelet, where / denotes deconvolution.

WebSep 7, 2024 · Seismic well calibration is a fundamental component within the seismic interpretation workflow. It is done to match the geological information observed in depth (at the well) to the seismic images acquired from the surface in time. WebThe seismic line traverses the Little Knife Oil Field in the Williston basin where the Zablotny #1 well was drilled by Gulf Oil (Rafavich, Kendall, and Todd, l984). Your task is to take a well (the Zablotny #1) drilled in the Little Knife Oil Field in the Williston basin and tie this to a North South seismic line across this field.
