Basemap: Selection Menu

The Selection menu allows you to pick a selection tool to help you create 2D and 3D seismic displays. The icon and associated hot keys are displayed in the menu. All of the selection tools are available on the Selection Toolbar and Hot Key pages.

Selection Tools

 Single Arbline: Once selected use the left mouse button (LMB) to start the selection and right mouse button (RMB) to finish the selection and launch the Seismic Viewer.  If the control key is held down when selecting a 2D line, Ctrl + LMB and the entire 2D line will be selected. The Seismic Viewer will only be launched after RMB is used allowing the user to select multiple 2D lines at once and launching the Seismic Viewer containing all of the lines in one step.  Depending on if Multi-Layer Seismic or Multi-Segment Seismic has been selected the Seismic Viewer will either display the segments stacked one on top of the other or side by side.  You can also RMB on any 2D line to launch the Seismic Viewer with the entire line displayed. Use the LMB to start a selection and hold down the Ctrl key to place a node and complete segment.  The Seismic Viewer will not be launched and this process can be continued to create several segments before using the RMB to launch the Seismic Viewer.

2D Arbline(Centered): Place the cursor on the 2D line where the seismic selection will start.  Use the left mouse button (LMB) to start the selection and then drag out the cursor to extend the seismic selection out equally in both directions from the starting point.  Once the desired length is highlighted use the LMB button to end the selection.  You can select multiple 2D lines at once by using the LMB to start the selection and the LMB to end it on multiple lines, then use the right mouse button (RMB) to launch the Seismic Viewer.  This is very useful for creating 2D seismic displays that have features centered in the Seismic Viewer.

Inline (East/West Display): Use the left mouse button (LMB) to start the selection and LMB to end it.  Use the right mouse button (RMB) to end the selection and launch the Seismic Viewer.  If the control key is held down when selecting a line Ctrl + LMB, then the entire inline will be selected and the Seismic Viewer will only be launched after RMB is used.  You can select multiple inlines at once by using the LMB to start the selection and the LMB to end it, and then use the RMB to launch the Seismic Viewer.
Note: The direction of the line can be changed from a Inline to an East/West display in the Selection Properties.

Crossline (North/South Display): Use the left mouse button (LMB) to start the selection and LMB to end it.  Use the right mouse button (RMB) to end the selection and launch the Seismic Viewer.  If the control key is held down when selecting a line Ctrl + LMB, then the entire crossline will be selected and the Seismic Viewer will only be launched after RMB is used.  You can select multiple crosslines at once by using the LMB to start the selection and the LMB to end it, and then use the RMB to launch the Seismic Viewer.
Note: The direction of the line can be changed from a Crossline to a North/South display in the Selection Properties.

2D Multi-Arbline: Click and draw out a square encompassing parallel running 2D lines and this option will highlight and select all the 2D lines in the square.  Use the left mouse button (LMB) to mark the first corner point of the square on a 2D line, use the LMB for the second point of the square on the same line.  Switch to second line and LMB to make the third and fourth corner points of the square.  Once the square has four corner points all the lines running parallel will highlight and be listed in the Current Selection dialog on the Basemap.  If you do not want all the lines in the square to be launched in the Seismic Viewer, use the Current Selection dialog to highlight and delete them.  Use the right mouse button (RMB) to launch the Seismic Viewer with all the 2D lines stacked one on top of another.  This feature is useful for creating a stacked multi-segment displays similar to those available in 3D seismic displays. 

Multi-Arbline:  Quick and easy way to launch several arblines through a 3D with equal spacing.  Use the left mouse button (LMB) to start the arbline then LMB to end the arbline and set the length and orientation.  The third and final LMB is to drag out the desired spacing for all the arblines in the seismic selection.  Use the right mouse button (RMB) to launch the Seismic Viewer.  Depending on if Multi-Layer Seismic or Multi-Segment Seismic has been selected the Seismic Viewer will either display the segments stacked one on top of the other or side by side.  The number of arblines in the square is determined by the Multi-Layer Step Rate.  

Multi-Inline (East/West Display): Quick and easy way to launch several inlines through a 3D with equal spacing.  Use the left mouse button (LMB) to start the inline then LMB to end the inline and set the length.  If the Ctrl key is held down while making the first LMB the entire line will be selected.  The third and final LMB is to drag out the desired spacing for all the inlines in the seismic selection.  Use the right mouse button (RMB) to launch the Seismic Viewer.  Depending on if Multi-Layer Seismic or Multi-Segment Seismic has been selected the Seismic Viewer will either display the segments stacked one on top of the other or side by side.  The number of inlines in the square is determined by the Multi-Layer Step Rate.
Note: The direction of the line can be changed from a Inline to an East/West display in the Selection Properties.

Multi-Crossline (North/South Display):  Quick and easy way to launch several crosslines through a 3D with equal spacing.  Use the left mouse button (LMB) to start the inline then LMB to end the crossline and set the length.  If the Ctrl key is held down while making the first LMB the entire line will be selected.  The third and final LMB is to drag out the desired spacing for all the crosslines in the seismic selection.  Use the right mouse button (RMB) to launch the Seismic Viewer.  Depending on if Multi-Layer Seismic or Multi-Segment Seismic has been selected the Seismic Viewer will either display the segments stacked one on top of the other or side by side.  The number of crosslines in the square is determined by the Multi-Layer Step Rate.
Note: The direction of the line can be changed from a Crossline to a North/South display in the Selection Properties.

Loop Tie: Displays a hollow square of seismic data with the first segment repeating itself at the end of the display.  Use the left mouse button (LMB) to select the first corner of the square, then use the LMB to select the second third and fourth corners.  Use the right mouse button (RMB) to launch the Seismic Viewer.  

Slice Selection: Once a slice is created use this icon to launch the slice from the Basemap. Hold down Ctrl and left click (LMB) on the 3D. This will launch the Slice Selection dialog and a slice can be chosen from the list of available slice files.  To only bring up a portion of a slice or to bring it up with a certain orientation use the left mouse button (LMB) to select the first corner point of the square to display the slice in.  Drag out the box over the desired area and LMB again to launch the Slice Selection dialog. The Seismic Viewer will launch containing only the area withing the square and it will have the same orientation as it was drawn.  To create a slice file, use the Create Slice application.  To launch the entire slice for the 3D, double click on the 3D. The Seismic Viewer will launch with the entire slice for the 3D and you can right click on the slice and use the "Versions" option to switch to a different slice. You can also use the Slice Toolbar on the Basemap for displaying slices.  

2D Mistie: Used to preform a mistie analysis over 2D data.  Use the left mouse button to click on a 2D intersection.  Multiple intersections can be selected at one time.  The Multi-Layer Step Rate is used to specify the number of traces to display on either side of the intersection.  Use the right mouse button (RMB) to launch the Seismic Viewer.  The data will be displayed side by side in the Seismic Viewer and the Mistie Analysis and the Zoom window will automatically be launched.  
Note: Specify the Mistie Time Range in the Selection Properties to have the Mistie Analysis window automatically launch with the same time range.

2D Intersect: Used to display 2D intersections in all four directions.  Use the left mouse button to click on a 2D intersection.  Multiple intersections can be selected at one time.  The Multi-Layer Step Rate is used to specify the number of traces to display on either side of the intersection.  Use the right mouse button (RMB) to launch the Seismic Viewer.  Each intersection will display four pairs of seismic side by side in the Seismic Viewer.  The first pair will start from the bottom of the intersection and work its way clockwise around the intersection.  

Multi-Radial:  Creates a full circle of evenly spaced segments centered on a single point.  Use the left mouse button (LMB) to center the display on this point.  LMB click again to specify the radius of the segments.  Use the right mouse button (RMB) to launch the Seismic Viewer.  Depending on if Multi-Layer Seismic or Multi-Segment Seismic has been selected the Seismic Viewer will either display the segments stacked one on top of the other or side by side.  The number of segments in the radial is determined by the Multi-Layer Step Rate.

Well Fence: Used to create an arbitrary line through wells on a 3D dataset.  Use the left mouse button (LMB) to click near a well and the selection will be snapped to the closest well bore. Use the LMB to make continuous segments from wells. If the Ctrl key is held down while making a selection with the LMB the fence will end and another well fence can then be started.  Use the right mouse button (RMB) to launch the Seismic Viewer.  The segments will appear side by side in the Seismic Viewer, with the first well selected representing the first trace in the display and the last well selected representing the last trace.

Well Path Arbline: Used to create an arbitrary line along the path of a deviated well. Use the RMB to click on the well and launch the Seismic Viewer. The arbline, which may contain multiple segments, will follow the patch of the deviated well as closely as possible, and display the traces that are closest to the segment line.

3D Pie:  Creates a pie shape of evenly spaced segments extending from a single point.  Use the left mouse button (LMB) to set the point the other segments will extend from  LMB click again to specify the lengths of the segments.  LMB for a third and final time to define the pie by dragging out the desired spacing for the segments.  Use the right mouse button (RMB) to launch the Seismic Viewer.  Depending on if Multi-Layer Seismic or Multi-Segment Seismic has been selected the Seismic Viewer will either display the segments stacked one on top of the other or side by side.  The number of segments in the pie is determined by the Multi-Layer Step Rate.

Jump Tie: Launches the Add Jump Tie dialog.  

Multi-Slice: Once a slice is created use this icon to launch a series of slices from Basemap. Hold down Ctrl and left click (LMB) on the 3D. This will launch the Slice Selection dialog and a slice can be chosen from the list of available slice files.  To only bring up a portion of a slice or to bring it up with a certain orientation use the left mouse button (LMB) to select the first corner point of the square to display the slice in.  Drag out the box over the desired area and LMB again to launch the Slice Selection dialog. Enter the slice value for the start and end slice you want to see, as well as an increment. Instead of launching every slice in your file, only these slices will be available for display. To create a slice file, use the Create Slice application.   You can also use the Slice Toolbar on the Basemap for displaying slices.

Add Ins: After selecting one or multiple data items on the map, a list of add-ins becomes available. These allow you to send information directly to other applications, eliminating the need to export data. A series of add ins are included in the installation files, but you can also create new add ins.
