Formation tops and markers can be spotted along the directional survey "worm" path.

This option can be found under the map Wells>Directional Survey>Depth Ticks and FM Tops On Survey Path menu option

Tops are identified by an associated well symbol plotted on the survey path.  The top's position along the borehole is defined by the measured depth or subsea TVD value of the formation top.  Options are available to assign a single symbol to a top for all wells or display the well symbol that is stored in the database with the top value.

Formation plotting along the well path is both enabled and disabled by clicking the "Active" check box at the bottom of the entry form.

Tops tab

The tops tab section defines which formation tops are plotted on the deviated well track. The "Available Tops" section contains a drop down list showing all tops defined in the project.

Tops which are plotted must first be selected from the "Available Tops" section and added to the "Selected Tops" list.

To select a top for display, select the top name in the drop down list, set the appropriate symbol and color options, and click the button to add the top the "Selected Tops" list.

You may change the symbol or colors for a selected top. First, click the top in the "Selected Tops" list. Then change the options in the "Available Tops" section, and click the button to update the top with the new values.

Remove individual items from the "Selected Tops" list by clicking the button. Clear all tops from the list by clicking the button.

Use Symbol From Data - Choose this option if you have assigned a numeric well symbol code to the individual top values for each well.

Use This Symbol - Choose this option to plot the symbol selected from the drop down symbol list.

Screen Symbol Color - Choose the color for the symbol drawn on the screen.

Plotter Symbol Color - Select the color for drawing the symbol on printed maps.

Options tab

This section contains the labeling and size options. The deviated borehole path can be labeled with the measured depth or TV subsea depth for each posted top. In addition, the borehole path can show ticks with depth labels at a specified depth increment.

Text Size (in) - Select or enter the height in inches for the depth labels.

Label Tops - Check this option if you want the depth for each plotted top to be labeled.

Symbol Size (in) - Select or enter the height in inches for all well symbols marking the position of a top.

Depth Tick Labels

"Do Not Label Depths"- No ticks and labels will be drawn along the well path except for those labels for each top (see Label Tops option).

"Label Measured Depth Values" - The well path is labeled at specified intervals showing measured depths down the well borehole.

"Label Subsea TVD Values" -  The well path is labeled at specified intervals showing subsea true vertical depths down the well borehole.

Depth Ticks Every - Select or enter the interval at which measured or subsea TVD values are to be labeled along the well path. The units for the directional survey data determine the units of this value.

Starting Depth For Ticks - Enter the minimum measured depth to limit drawing ticks and labels along the well path. This option can be minimized over posting near well surface locations.

Enlarge Sizes With Zoom - Select this option to have the label and symbol sizes increased whenever you zoom in on an area.
