Seismic Studio Tutorial - Part 2“Trace Visualization and Refraction Picking” Boulder, Colorado USA May, 2004 Trace Display Windows Available under Pick on the Menu Bar Conventional Pick Window Shows one record at a time Is map-driven Can display in source, detector, bin or common offset planes Can apply filter and gain Can display geometry error vectors Can display all 3D lines or one line at a time Can be modified to display traces in different colors Is used to pick refracted arrivals Control Pane 1 Tab 1 – Base map – can display map view of any database value Tab 2 – Trace info – can track trace info for any trace in Trace Display Pane Tab 3 – Source info – can track source database info for any trace in Trace Display Pane Tab 4 – Error vectors – can show geometry error vectors for current source or detector gather Tab 5 – Detector info – can track detector database info for any trace in Trace Display Pane Control Pane 2 Tab 1 – Options – user can change planes, change map view, change mouse mode, etc. Tab 2 – Hot Keys – user can map picking and navigation to any key on keyboard Tab 3 – Map – can display map view of any database value (same as Base map in Control Pane 1) Tab 4 – Error vectors – can show geometry error vectors for current source or detector gather (same as error vector tab in Control Pane 1) Tab 5 – Pilot – interactive control of autopicker. How to modify the trace display This next part will show you how to change the trace display by applying complex moveout. In Seismic Studio this is called “Defining an LMO trend.” How to modify the trace display This next part will show you how to change the trace colors How to modify the trace display This next part will show you how to limit the trace display to a user-specified offset range. How to pick refracted arrivals This next part will show you how to limit the trace display to a user-specified offset range. The first thing you will learn is how the picking controls work and how to customize them
