OVERVIEW: The Card Viewer window allows you to view dynograph surface and downhole cards, and to view the XDIAG analysis output. It can also be used to collect cards and to change certain controller setpoints. When you change from one well to another in the Well Group Tree, the window is automatically updated with information for the new well.
NAVIGATION:
From the Main Client window: 1. Click on the Well menu.
2. Click on the Card Viewer menu item. OR
Click on the Card Viewer button from the Toolbar.
• Card Plot Area – displays selected dynamometer cards and the calculated downhole card • Command Panel – utility buttons for collecting cards and exporting them to file
• Card Library – displays a list of stored dynamometer cards, with time/date stamps • Input Data – displays input data used in the analysis (sources are database and POC) • Output Data – displays calculated parameters from the XDIAG analysis
• Analysis Data – displays plain English report of the condition of the entire system
1. Card Plot Area
When first opened, the Card Plot Area displays the selected surface card and if available the downhole card for the well selected from the Well Groups Explorer on the left side of the Main Client window.
The cards displayed in the plot area are indicated by a small, colored box just to the left of the Time/Date stamp of the cards listed in the Card Library. The color of the box next to each Time/Date Stamp for the card matches the graph color in the Card Plot area so you can distinguish which plot belongs to a particular card.
2. Card Plot Area Customization Menu
The display of the Card Plot can be customized by right-clicking anywhere in the plot to open the customization menu which is shown to the right. These settings are retained based on the last time you changed them, so you do not need to set these every time you use the client.
A brief description of each menu item follows:
• Clear All - clears the Card Plot Area.
• Clear All Except Current – clears all cards except the last one displayed. • Print - prints currently displayed cards.
• Overplot Retreived Cards -
• Show POC Downhole Card - displays the POC Downhole card.
• View Downhole Card - displays the calculated downhole card from the XDIAG analysis.
• View Predicted Card - displays the RODSTAR predicted surface card. • View Load Limits - displays the load limits set for this well.
• View Set Points - displays the set points for this well.
• View Legend - displays the color and names of all the visible cards. • View Toolbar - displays the graph's toolbar.
• View Torque Analysis – view Torque Analysis on Current Card
• Card Selection - indicates which cards are automatically displayed when the card viewer is started or a different well is selected from the Well Groups Explorer.
o Last and PO - is the most recent card and the most recent pump-off card.
• Show Grid Lines - displays Card Plot Area grid lines.
• Full Screen - enlarges the graph to a full screen for better detail. Toggle the check mark to enlarge the plot or to restore to normal size.
3. Card Library
The Card Library is a list of cards collected for the
currently selected well. In this figure, the colored boxes to the left of the Time/Date stamp of each card indicate that these are the particular cards being displayed (and represents the color of the card in the graph).
XSPOC runs a task once per day to collect and analyze cards. This time is configurable, but is typically run in the early morning hours between 2am and 6am. If the well runs 24 hours per day, XSPOC will collect only a single “Current” card, since the Startup and Shutdown cards for
this well will often be quite old and not pertinent to how the well is currently operating. If the well run’s less than 24 hours per day, XSPOC will collect both the Startup and Shutdown cards. Although configurable, the system will only analyze the Startup cards since this is normally most representative of how the well normally runs.
• Date is the date and time (24 hour format) of when the card was collected. • Type
o PO/SD represents cards stored when pump was last turned off. The card collected is the most recent pump-off/shutdown card stored by the POC at the time of collection.
o Startup represents cards stored when the pump first started up. The card collected is the most recent start-up card stored by the POC at the time of collection.
o Current represent cards collected while the well was pumping at the time of collection.
• DH indicates whether a downhole card has been calculated for that well. If the card does have a downhole card then "Y" will appear in the column; otherwise, it will be left blank. • Save will mark that card to not be deleted after the standard 30 - 60 days. The XSPOC
administrator sets the duration of time for which cards can be saved. Double-clicking in the box will toggle the “Y” for the particular card.
• Note indicates whether a note has been made for that card. Notes can be added or modified by double-clicking on this box. Any notes made here are automatically added to the ‘Notes’ history.
Selecting the card and then pressing the delete button on the keyboard will permanently delete that particular card. XSPOC will ask for confirmation of the deletion before taking action.
4. Input Data
The Input Data for the selected well and the selected card is obtained from information stored in the database. This information is collected from user input and from the POC.
• Runtime (Hrs) • SPM • Str. Length ('') • Pmp Diam ('') • Pmp Depth (ft) • Tst Date • Tst Gas (msfd) • Tst Oil (bpd) • Tst Water (bpd) • Tst Gross (bpd) • SurCap@24 (bpd) • Pumping Unit • Cycles, Yest
• Idle Time (min) can be changed by clicking the button next and entering new idle time values. You will be prompted for the control password, if it has not been entered already during the session.
• Inf Prd, Yest
5. Output Data
The Output Data for the selected well and the selected card displays values calculated by XDIAG using the input data and surface card.
• DH Cap@24 (bpd) • DH Cap@RT (bpd) • DH Cap@RT, Fillage • Pump Efficiency (%) • Fluid Load (lbs)
• Buoyant Rod Weight (lbs) • Dry Rod Weight (lbs) • Pump Friction Load (lbs) • PO Fluid Load (lbs)
6. Command Panel
The Command Panel is a series of buttons that aid in collecting dynamometer cards and in exporting them to file. Directly above the Get Card button, the POC's model type for the selected well is displayed.
• Run XDIAG on Card – prompts XSPOC Client to perform an analysis from the XDIAG software. • View Analysis Report – opens the analysis report for
the selected card
• Email card to Theta will create and send a card via email to Theta Enterprises. When clicked, you will be prompted for email addresses before card can be sent. This feature must be configured by an administrator to work properly.
• Export Card to File – allows the user to save the current card, selected cards or all cards to a dynonometer file.
Retrieve Cards Section
Get Card commands XSPOC Client to pull selected card type from POC. Type Options
• Current - data from latest stoke.
• Startup - the first card when pump was last started.
• Pump Off/ ShutDown - the last card before Pump was last turned off. • PO/ShutDown Buffer - gets the last several strokes prior to the shutdown
• Prev SD/PO Buffer – • Standard –
• Startup (No MPT) –
• Sample 10 Live Strokes - pulls card for the next 10 strokes (not available on all POC types).
• Quit Live Sampling - cancels the Sample 10 Live Strokes action.
7. Analysis Data
The Analysis Data box is a description of the condition of the rod pumped system as determined from the selected surface card. It explains what is happening at the pump at the time of the selected card collection, provides information on equipment that is overloaded, and lists possible sources of error within the data and corrections that may have been made.
The text in this box constitutes the second page of the analysis report, which may be opened by clicking the View Analysis Report button in the Command Panel of the Card Viewer Window.
