Card Viewing Options

The Dynagraph Viewer includes a variety of options to customize card display. These include the ability to toggle card plot elements, overlay cards in the view set, and show or hide a corresponding downhole plot.

On the card plot, you can toggle visibility of data points (see below), net stroke, and fluid fill setpoint. When one of these elements is visible, a check mark appears next to the command in the View menu. Click the command to toggle the element’s visibility. Visibility settings are preserved across Dynagraph Viewer sessions. See Customizing the Window for information about toggling other window elements.

The following card viewing options are described below.

Displaying Mark Points

Select Mark Points to view all data points (load/position pairs) that were used to construct the card graph. The number of these data points is specific to the device. Typically, 100-200 points are returned, all of which are plotted. Points are displayed as small circles along the curve. You can mouse over a point to display its position and load information in a tooltip. See Card Details for information about displaying a list of all raw data for a card.

Displaying Net Stroke

Select Net Stroke to display the net stroke as a vertical bar on the downhole graph, which you can move. When you move the mouse over the line, a tooltip appears with the net stroke value at the given position. This value is calculated as follows:

Net stroke = current position of vertical bar x pump speed x pump coefficient

The pump speed is retrieved from the card if available, or from the details panel. The pump speed UDC is WPCSPEED00, and the pump coefficient UDC is WLPUMPCO00. See a CygNet administrator for further information.

Overlaying Cards

Overlaying multiple cards in the plot area can aid in card comparison, especially when looking for fine curve differences. If the Overlay Cards option is selected, all card requests will be automatically overlaid. Otherwise, a retrieved card will replace the card currently being viewed. The maximum number of cards that can be overlaid is user-configurable, with a default value of 30.

To Turn On/Off Card Overlaying

To Configure the Maximum Number of Cards Overlaid

  1. On the View menu, click Max Cards to Display.
  2. In the dialog box, enter an integer value between 5 and 50.
  3. Click OK.

Selecting a Card Set

Any card or a subset of cards stored by the DDS can be selected and viewed in the Dynagraph Viewer. The number of cards stored is configured per card type in the DDS (for the data group’s Transaction retention settings). When a set of cards is selected, they are added to the view set, unless a selected card is already displayed (duplicates are not displayed).

To Select a Card Set

  1. On the View menu click Select Card Set or right-click in the graph and select View from the context menu. Or click the Select Cards button Select Cards on the toolbar. The Choose Cards to View dialog box appears. This dialog box lists all card transactions stored in the DDS.
  2. In the Card Type drop-down menu, select a card type to filter the list, or leave "<All Cards>" selected to view the complete list. You can also order the list by Card Type and Date Requested by clicking the appropriate header in the list box. The arrow indicates whether the list order is ascending or descending.
  3. Select the set of cards to view. To select multiple cards, hold down the Ctrl key while you click them.
  4. Click OK.

Paging through Cards

You can page backward and forward through the view set using the Next and Previous commands. When a card is selected, its label will appear slightly larger. The order of the cards in the view set can be determined by their labels. This is the order in which they were added to the view set, not their chronological order. When only one card is in the view set, these commands are disabled.

To Move to the Next Card in the View Set

Do one of the following:

Clearing Cards

Two functions exist for removing cards from the view set: removing cards individually and clearing all cards. These actions cannot be undone, but it is possible to re-select stored cards using the Select Card Set command (see Selecting a Card Set).
