Displaying Formation Tops

Cross Section: Tops > Display Options...

Selecting tops and defining display attributes for a cross section is done from the Formation Display Options dialog.

1	Well indicator bar	Visual indicator of which well(s) contain the highlighted top.
2	Available tops pane	Lists all tops or a filtered list of tops available for the cross section. Selecting or double clicking a top on the list adds it to the Displayed Tops list. The Available Tops columns can be sorted when showing all tops The list can be filtered by well, formation or source if needed.
3	Filter by Well pane	Lists all wells in the cross section. Checking a well will filter the Available Tops list to only include tops and show depths in the selected well.
4	Displayed Tops pane	Lists tops selected for display on the cross section. Display attributes for each top are accessed by clicking the Attributes cell.
5	Option tabs pane	Options tabs provide general, miscellaneous and fill options for the cross section and sort controls for displayed tops.

Available Tops

Src	Filter field for Formation Source. Multiple sources can be listed using standard wildcard (?) searches.
* Examples: ??S* - Returns only values with 3rd character of " S " GS* - Returns only values that began with the characters " GS "

Columns in the Available tops pane can be sorted by clicking a cells heading.

Filter by Well

Selecting a well from the Filter by Wells list will display only the tops (with depths) of the selected well in the Available Tops list. Only one well can be selected at a time.

Tabs pane

The tabs pane provides multiple options to assign display attributes to the cross section. It consists of three tabs:

General
Misc
Fill Options

General tab

Top Connection Method	Do Not Connect Tops Draws small ticks at each well. Connect Tops to Track Boundaries Draws tops straight across log tracks connecting tops from well to well. Connect Tops to Bore hole with Straight Line Draws straight lines between wells. Connect Tops to Bore hole with Curved Line Draws tops using a spline function fit to tops that results in a more realistic structural picture.
Label Method	Label Tops For each top, this option uses the label settings set on the Style tab. Essentially this option allows top labeling. Do Not Label Tops Disables all formation top labels on the Cross Section Module. Opaque Label Box Uses opaque label boxes around formation top label. This option is good for displaying labels over log shading. Label with Actual Name of Alias This option continues to use formation top aliasing, but will plot the actual name of the formation top rather than the aliased name.
Repeat Tops	Ignore Repeat Tops This option does not plot repeat tops. Only the first top listed will appear on the cross-section Indicate Top with Markers This option draws a small triangle (matching the color of the top) at each top location in the cross-section. This makes it easier to recognize repeat tops along a well bore. These markers also indicate which tops are repeats by not filling in the triangle for any repeat value.
Settings	Load Loads saved Tops Parameter file (.XTP) Save Saves selected tops and display options to .XTP file for later use.

Misc tab

Draw Tops After Log Curves	Sets the render order to draw the Tops after the log curves.
Always Post SSTVD when SS requested	Always displays SSTVD values as SS values.
Post all Tops in Depth track	Selects all tops in depth track and clears all others.
Plot Labels using top color	Uses selected top color as label color
Smallest label on screen	Sets minimum size for label
Line drawing step size	Determines smoothness of the curve.
Skip Tops with Quality Codes Containing containing [ ]	Ignores tops with selected quality codes. Multiple codes can be entered using a delimiter between codes.
Reset	Clears all selected tops and display settings.

Fill Options tab

Do Not Fill Between Wells	Turns off the fill between wells.
Sorting	Sort Tops Attempts to automatically sort formation tops in increasing depth order before drawing any fills, ensuring that the shading between tops is correct. Do Not Sort Tops Disables automatic sorting. This option is best used where the automatic option incorrectly shades tops because of pinch-outs and missing values. Note that the tops on the Displayed Tops List must be manually sorted from top to bottom.
Track Fill Examples	Do Not Fill Tracks No formation top fill in the depth tracks. Fill all Tracks Fills all displayed depth tracks. Example Fill Depth Track Only Fills only the depth track immediately underneath the well symbol. Example Fill Track 1 Fills only the selected depth track.Example
Advanced Fill Options	Only fill between tops that occur in all wells Fills only between tops that occur in all wells. Tops that have a null value for any well on the cross section will not have any fill. Fill between tops that occur in adjacent wells Fills any top that occurs in two adjacent wells. This option is more tolerant of missing tops.
