He has extensive experience in subsurface mapping, seismic stratigraphy, sequence stratigraphy, seismic interpretation, petroleum geology, and geophysics. The tutorial outlines how to tie well data to seismic in order to determine which sesimic events occur to which geologic markers. Be able to interpret horizons and faults on seismic data. When a ray encounters an inhomogeneity in its travels, for example a lithological contact with another rock, the incident ray transforms into several new rays. The first image below is illustrating the functionality of the 3D Autotracker. The seismic interpretation window gives the user a classical 2D view of seismic data. Seismic attributes are any measurable property of seismic data and are produced to help enhance or quantify features of interpretation interest. icon on the Tools toolbar as shown in .

Machine learning in seismic interpretation uses computer algorithms to help geologists understand the relationships between large amounts of geological data or information. the seismic data, picking the first onsets, putting together the picked traveltimes, assigning to specific layers, doing the layer inversion and refining the resulting model by raytracing (chapter I to chapter III). After initial inspection of the data, further analysis can be performed. To create an accurate picture of the subsurface, we must remove or at least minimize artifacts in these records related to the surface upon which the survey was performed, artifacts related to the instrumentation and procedure used, and noise in the data obscuring the subsurface image. Seismic stratigraphy is a model-driven method that follows the principles of field geology and the well-based study of subsurface sedimentology, and it assumes that seismic reflections can duplicate geologic correlations.

In Section 2 we outline a general methodology for solving the inverse problem as an optimization problem. The first phase started in the late 1960s, when shear-wave source reflection data were collected with vertical seismic profiles (VSPs) to assist interpretation (Cherry and Waters 1968, Erickson et al 1968), and this continued to the second phase until the mid-1980s, when the main drive was to improve seismic resolution using shear waves (Anno 1987, Tatham and McCormack 1991) due to their … under the . Introduction: Seismic interpretation, whether for hydrocarbon exploration or geotechnical studies, is the determination of the geological significance of seismic data. Some tutorials may only involve drawing simple diagrams, but many are computer-aided (PC based) with graphics output to give insight into key steps in seismic data processing or into the seismic response of some common geological scenarios.
