Seismic Miscellaneous Tab

Use this tab to set a variety of display options for the Seismic view. WinPICS will save the preferences as defaults for your current project. View image

This tab has the following options:

Horizon Picking

Manual Picks Have Zero Amplitude - Clear this check box if you want to save amplitudes calculated from manual or sticky picking. This option is selected by default because amplitudes calculated from a manual or sticky horizon picking are often meaningless and are best not posted on amplitude maps.
Guard Against Lateral-Delete Combination - Clear this check box if you want to quickly delete data for an entire line. This will enable you to use the lateral-delete function, which like the lateral picking mode, enables you to click on a single point on your event and have WinPICS delete the interpretation across the entire line until it can find no suitable pick.
Remember that delete mode is a temporary mode. Once you complete one delete action, WinPICS will revert back to the previous picking mode. Re-enable this protection as soon as you finish deleting the data.
<Picking Time Gate Window> - Click this button to open the Set Picking Gate dialog box, where you can control how your data is picked by auto picking, lateral picking, and volume picking, by limiting how far up and down the trace WinPICS will search for the next pick. You can define the picking gate by Zero-Crossings or by the Entire Gate.

Horizon Thickness

Follow these steps to set the default horizon thickness.

Set a line thickness in microseconds for drawing horizons on your seismic display. Enter 0 (default) to draw horizons with a line thickness equal to one sample, which is usually 2 ms. If you have seismic with different sample rates, use the minimum and maximum pixel size to help control the variation in horizon thicknesses.
When you zoom all the way out on a map and have the line thickness set to one sample, it may be difficult to see the horizon. Set a multiple to increase the horizon line thickness with the zoom state. The default is 2. Note the maximum thickness of the line is controlled by the maximum number of pixels (below).
Set the minimum and maximum allowable thickness for horizons on the seismic display in number of screen pixels. The default is 1 and 4.

Fault Picking

Cleanup When Re-Picking up to Faults - Select this check box to set WinPICS to clean up old picks around your fault when the angle and throw of the fault leaves disconnected picks from previous horizon picks.
Delete Fault Corner Creates Gap - Select this check box to have WinPICS remove the adjacent fault segments and the corner when you delete a fault corner. If you clear this check box and delete a corner, WinPICS will join the adjacent fault segments.

Fault Guard Zone

Enter an integer between 0 and 1000 for the guard zone. The guard zone is the area around the fault where horizon picks are cleared when a fault is marked, edited, or interpolated.

3D Volume Picking

Limit Volume Picking to Traces in Window - Select this check box to disable your ability to make volume picks beyond the limit of the traces seen in the Seismic window. By default, this check box is cleared, which means you can make volume picks that you cannot monitor from the Seismic window.
Lateral Pick Holes When Volume Picking - Select this check box to use lateral picking to fill in the next line of traces when you're volume picking. If this check box is cleared, WinPICS applies lateral picking to only one trace in zones where no picks are available on the guide line.
