AccuLink  Allows a user to retrieve general well information and well tops directly from an AccuMap database.

Active   Only active files will appear on the Basemap and in dialog menus.  Seismic, culture, grids, rasters, faults and horizons all have an Active flag associated with them.

Active Dialogs  Menus or windows of information that are associated the Basemap. These windows can be attached, or "docked," to any side of the parent window, or "floated" in their own independent miniature window.  These include Colorbar, Criteria Legend, Current Selection, Line Tracker, Scale Bar, Status Bar Navigation Pane and Well Posting.

Arbline Selector   A tool that allows you to select 2D and/or 3D seismic for display in the Seismic Viewer. The left mouse button is used to select seismic segments, and right click is used to launch the Seismic Viewer.

Bubbles   Allows user to scale well symbols based on numerical information.

CDP   Common Depth Point numbering for a 2D. Typically this value increments by 1.

Co-blending   A tool in the Attribute Viewer that allows you to visually blend two or three versions of a volume together.

Criteria   Allows user to post a marker shape on a well symbol based on a specified condition.

Culture   Drawn or imported objects on the Basemap that include grid lines (township, section lines, lsd., .etc), contours, polygons, land boundaries, bodies of water, roads, pipes, etc.

Current Role    The role of the Current User. The Current Role determines the privileges you have in a project with respect to creating, re-assigning and deleting data.

Current User   The user who is currently logged into the project. The Current User is associated with a specific Window Login ID. This can be configured in User Properties.

Curve Datum   A value associated with a velocity curve that allows you to adjust the datum of a velocity curve independently of a well datum. 

Data Pipeline   Allows you to retrieve data directly from various configured databases, and bypass the need for exporting and importing data.

Despike   A tool used to remove "spikes" or bad data points from grids or horizons.

Docking View   A window, such as an Active Dialog, that can be attached, or "docked", to any side of its parent window, or "floated" in its own independent window.

Dongle   License key used as a form of software security to prevent the illegal unsanctioned use of SeisWare. Most SeisWare dongles are green USB keys.

Duplicate Tops   Formation tops with identical name, source, and depth.

Ends and Bends   The angle used to specify the amount that a 2D line can change direction before the change is drawn on the Basemap.  2D lines will appear smoother on the Basemap.  For example if 5 degrees is set then any 2D line that has a bend of 5 degrees or less will draw straight.

Fixed Size (Inches)   Text sizes that are fixed and will not scale as you zoom in or out.

Formations   A geological formation.  For a Top to exist in SeisWare the Formation must also exist.

Generate Synthetic   Uses the sonic log and velocity curve to create a synthetic track that can be placed in the Seismic Viewer.  A generated synthetic can be manipulated within the Seismic Viewer.

Goto   Used to center the map on the data item selected and highlight it.

Grid   Coordinates that contain a z value to represent a surface (time, depth, etc.).  Can be seen as a colored surface on the Basemap and is usually associated with a contour layer.

GWC   Grid, wells, and culture. Files usually used to setup a project.

GWI   General well information including UWI, Status, Depth Datum, and locations.

Header   Beginning of a SEG-Y file that contains all the information regarding the SEG-Y files contents.  The header can be viewed in a SEG-Y viewer.

Impersonating The effective user of a project. A Current User with a role of Administrator or Data Manager can impersonate another user associated with a project, so that new data is associated with that user.

Inactive   Files that are in a project but not visible in layer properties or any other dialogs other then the properties dialog.

Index File   File used to map individual traces in a 3D SEG-Y file to their respective lines.  All SeisWare 3Ds have one of these files and the file must reside in the same directory as the 3D.

Inserted Synthetic   allows the user to insert a SEG-Y synthetic track into the Seismic Viewer.  This file can be bulk shifted but not manipulated in any other way.

Key Map   The portion of the Basemap that is currently visible in the window.

Keyword   A mapping of the byte locations for a SEG-Y file.  Usually created when loading seismic.

Layer Visibility   Allows user to define which layers are visible at specified scales on the Basemap.

Line Sequence Number   Inline numbering for a 3D, typically displays as a step function in a graph.

Local File Cache   A local file location that stores copies of data that exist on the network. This allows for faster access to the file. 

LMB   Left mouse button.

Main Launcher   Main window (bar) in SeisWare.  Many of the features in the software can be accessed from this location. 

Montage Editor   Allows user to alter the print out appearance by placing objects and defining the size of those objects in a custom manner.

Multi-Layer   Seismic Viewer will display each segment selected on top of one another within the same viewer.

Multi-Segment   Seismic Viewer will display each segment selected side-by-side within the same viewer.

Owner    The user in a project that owns specific data items. The Owner is the user who creates or imports data. The Current User may be Impersonating another user in order to ensure that data has the correct Owner.

Posting   Placing text information on the Basemap.  Can be applied to wells, seismic, horizons, and grids.

Posting Tolerance   This value is used to ensure that values are posted when they increase irregularly. For example if shot values are not exact numbers and the software may be attempting to post a value of 100, and the nearest shot is 100.05, this will still be posted if the posting tolerance is more than .05.

Project List   Text file that contains the information contained in Project Properties including the project location and description.

User shift   A shift applied to a velocity curve that allows the curve to display in the correct location without applying an unrealistic replacement velocity. 

Quick Iso  Allows a user to select 2 horizons and create and isochron or amplitude on the fly which will not be saved to the database.  Quick Iso results will be displayed with quotation marks around them.

Raster  A picture placed on the Basemap, typically a geotiff image.

Ribbon  Color on the Basemap.  Ribbons may be 2D and 3D horizon information, grid information or well information.

RMB   Right mouse button.

RSA   Rock Solid Attributes™, a tool used to generate attribute volumes.

SEG-Y Viewer  Window where SeisWare displays the header information of a SEG-Y file.

Shot Sequence Number  Shot point numbering for a 2D, typically it increments by 0.5.

Source  A name used to denote where well information was obtained.  Can represent a specific person or software package.

Tops  Formation depth value for a well.

Trace Sequence Number  Crossline numbering for a 3D, typically displays as a saw tooth pattern in graph.

Variable Size (Meters)  Layer objects which are drawn the exact size specified.  Objects will become larger or smaller as you zoom in and out.

Wavelet Analysis  Tool that will perform a cross correlation or Manhattan distance comparison using multiple wavelets.  Also referred to as facies analysis.

Working Set  Working set files are the currently active version for a given line. These will be the default versions that appear on the map, or in any dialog.
