XSPOC
Modern Design and Simulation of Deviated and Vertical Rod Pumping Systems

  • Overview
  • Ease of Use
  • Expert Analysis
  • Hardware Interface
  • Theta Software Integration

XSPOC is a comprehensive well management system that fully integrates all of Theta's software. It uses modern communication technologies to link real-time data to Theta's powerful diagnostic and design tools. XSPOC is not just for pump-off controllers anymore. It now supports other wellhead devices including submersibles and flow controllers. Other devices are being added all the time. Just take a quick look at the powerful features of XSPOC.


Features:



XSPOC performs many functions and supports a broad range of devices.

  • Full host-based POC control and data acquisition.
  • Open database using Microsoft SQL Server (allows easy integration with customer databases).
  • Integrated with XDIAG to provide automatic expert diagnostic analysis for each well.
  • Client/Server architecture, fully network capable, with unlimited number of client connections.
  • Scalable: can be used to automate fields with few wells or with thousands of wells (currently used in a field with over 3500 wells).
  • Data history graphs with trends of pump efficiency, runtime, production, or any other variable measured, or calculated by XDIAG.
  • Full well control (startup, shutdown, parameter downloads, etc.)
  • Statistical Process Control (SPC) limit methods used to automatically signal when a critical parameter goes outside statistical limits.
  • Supports all modern POC hardware.
  • Automatic alarm/shutdown alphanumeric paging.
  • Automatic well control based on other conditions (facility alarms, time of day, etc.)
  • Real-time dial-in support.
  • Integrates with RODSTAR, XDIAG, RODDIAG, and CBALANCE, and can read dynamometer files created with DYNOSTAR.
  • Powerful Grouping / Exception Features that are user selectable based on any value in the database (including analysis history).



User Friendly Interface

XSPOC is very easy to use. In fact, most users find they can be highly proficient in a short time and with very little training. It allows you to simultaneously view a list of wells, the surface and downhole dynamometer cards, important parameters for the well, and the expert diagnostic analysis. The wells can be grouped in any way you want and you can easily switch from the dynamometer card screen to the well status screen, the trending screen, or any other screen available. Or you can keep all screens open simultaneously.


Grouping Wells

XSPOC makes finding problem wells very easy. It's navigation revolves around customizable well groups. From the start, wells are viewed through exception groups such as "Enabled", "Disabled", "24 hour", "Alarms", and the encompassing "All". By expanding these groups, the wells that meet that criteria are exposed. From a practical standpoint, if someone want's to know all the wells in alarm just expand the "Alarm" group.

Additionally, this same functionality can easily be customized to include organizational or geographical groups, like operators or fields. If there is a way to describe the critiria for a group of wells, the customer is able to create that group, thereby allowing full customization of this feature.

All of the system reports are built to work with these groups including automatic morning reports.





How are my wells operating right now?
The group status screen allows users to view the current state of wells at a glance. This screen uses intuitive colors to draw attention to problem conditions. Not only can the user view the status and alarm states for each well, but there are also over fifty other columns of collected data available. Each user is allowed to customize the columns that they want to see, so it is very flexible.

Other features of the Group Status include quick sorting of any column and easy entry of user comments. This screen also allows real time control of the wells, including starting, stopping, clearing alarms, etc.


What's really wrong with my well?
One of XSPOC's most valuable screens, the card viewer collects, displays, and analyzes dynometer cards. Even though XSPOC is set to collect cards and to perform XDIAG's diagnostics on every well every night, there are times when it might be necessary to pull the latest startup, pump-off, current, or buffer from the POC. It's a snap. Select the card then push the "Get Card" button.

The card is delivered to the card library. This library catalogs past cards making it easy to compare multiple cards (including their downhole or RODSTAR's predicted card) at the same time. Just double click the card to display it. The library also provides the ability to make notes on each card and mark a card to be saved forever.

The card viewer also allows specific properties, like POC setpoint, malfunction point, and load limits, to be set visually. Just drag and drop it to the its new location.


Is my well operating differently than before?
The Data History is a timeline of all well data including analysis calculations and well events. It can show trends of falling production or show early signs of pump wear. Any trended parameter can be analyzed using statistical process control which automatically sets upper and lower control limits. Or the user can override the automatic limits and set his own. Parameters falling outside these limits are easily viewed on the Group Status screen.

The frequency of data storage and the amount of data retained is customizable by the customer.
State of the Art Expert Analysis
Along with retrieving and storing data, XSPOC gives a detailed diagnosis in a very understandable format.


eXpert DIAGnostic analysis software
XSPOC contains the powerful XDIAG expert diagnostic analysis software. It provides automatic expert diagnosis of every well, every day. XDIAG uses pattern recognition and artificial intelligence to identify the pump condition, fluid level, pump friction, etc. and creates an expert report for each well in plain English.

XDIAG also recognizes problems with the input data and either automatically corrects the data or notifies the user of the problem.


What if my input data is bad?
While XDIAG would favor having perfect input data we also understand this is the real world. XDIAG will identify many data problems and can automatically correct most of them. These data corrections include fixing errors with load cells, position transducers, top-of-stroke settings, stroke length inconsistancies, etc. Diagnostic software which does not perform these corrections will give much less accurate results.
What hardware works with XSPOC?
XSPOC uses modern communication techniques to bring information into the XSPOC system.


What devices does XSPOC work with?
XSPOC is compatible with all the major pump-off controllers availible on the market. Theta also supports other devices including submersible controllers and flow controllers. Theta is actively working on adding more wellhead devices, including flow controllers, plunger lift, and gas lift. XSPOC can also communicate with any Modbus-compatible device for other applications including tank battery monitoring and other RTU/PLC applications.


How do I tie XSPOC to my devices?
XSPOC supports all of the communication technologies being used in the oilfield today. These include radio telemetry, hardwire communications, ethernet, CDPD, OPC, DDE, satellite, etc. XSPOC can even communicate over the internet. All of the communication protocols have been designed by Theta to maximize performance with these various communication methods.
How will XSPOC fit into my existing systems?
XSPOC is the only system of its type that is built entirely on an open SQL database. This allows XSPOC to fit in nicely with your existing data systems. Our competition uses proprietary closed databases that require special tools to access the data.

 



Why Microsoft SQL Server?
Microsoft SQL Server's popularity continues to grow. It's easy to use, easy to add and change data, and can be used (imported or exported) by a wide variety of data aware applications. The best aspect is that your company can link any number of applications in the XSPOC database to extract or even add data without even using XSPOC.


Does XSPOC work with Access or Excel?
Many users are already using Microsoft applications such as Access and Excel. These products can be linked directly to XSPOC data, allowing users to query, analyze, and report data in ways they are already familiar with.


I already use RODSTAR. How does it fit in?
All of Theta's other products are tightly integrated with XSPOC. If a user wants to redesign a well using RODSTAR this can be done by clicking on the RODSTAR button on XSPOC's toolbar. This elimates the need to re-enter production and equipment data because this information is already stored in XSPOC.


I already have well data in other systems. Can I use it?
Most oil companies already have data that is needed by XSPOC in other databases. This may include information such as rod strings, well test data, pump size, etc. With the open architecture of XSPOC, it is easy to integrate this information so the user is not burdened with entering data twice. 


Can the system inform me of problems?
Key people need to know when wells are down or outside acceptable levels. XSPOC can automatically notify users via alpha pagers and voice call out.


What about automatic reports?
The XSPOC system has a flexible reporting system that allows users to not only view reports but to send them to printers, web servers, and email. The reports can be scheduled for automatic printing using any well group that the customer specifies. While the built-in reports should meet all the users needs, custom reports can be easily generated using Microsoft Access or other reporting tools.
