WinGLUE® Data Sheet

Table of Contents


  • Windows Vista
  • Windows 7
  • Windows 8
  • Windows 8.1
  • Windows 10

    • Benefit: These are the most popular operating systems in use today and WinGLUE® works equally well with each. WinGLUE® is highly flexible and configurable, especially when it comes to data source configuration. PCs running WinGLUE® can access data from the same data source.


  • System CPU
    • 1.0 GHz or higher CPU

  • Disk Space
    • 150 MB Minimum

  • RAM
    • 2.0+ GB RAM is highly recommended

  • Math coprocessor
    • Not required, but execution speed of modeling calculations will be VERY slow without one. Most processors (e.g. Pentium processors) have a math coprocessor built-in.


  • Compatibility with SQL databases - Oracle, MSSQL, Firebird, and databases that provide support for the ODBC interface (support for other SQL databases can be added upon request)
    • Benefit: Able to access data using industry standard tools for custom queries and report generation. Interfacing to other company databases to promote interoperability. (Example: Export of optimized lift gas distribution to CAO system for setting well injection flows. Potential for future interoperability is the update/approval process for entering well test into a company well test database.)

  • Ability to work with multiple databases
    • Benefit: Able to connect to multiple data sources concurrently (local and/or remote). Able to improve productivity by sharing information. Promotes use of central databases which helps gas-lift teams work surveillance issues and monitor field assets while also allowing each individual to use a local database for personal design work and "what-if" type analysis.

  • Able to handle multiple users on a networked database.
    • Benefit: This is an inherent benefit of the networking concept. Productivity improvements are realized by sharing information between Analysts, Engineering, and Management.

  • Remote database access through dial-up connections into a company‚Äôs computer network.
    • Benefit: Personnel are not tied to an office to get the latest information for analysis and troubleshooting of wells.

  • WinGLUE® performs its own database management. If any schema upgrades to a WinGLUE® database are necessary, like when a new version of WinGLUE® is installed, it will automatically perform them.
    • Benefit: No need for hiring someone to be a database administrator for WinGLUE®. The program manages itself, to provide the user with trouble free data management.

  • Populate databases through importation of data from Microsoft Excel-style "csv" files.


  • The basic framework for WinGLUE® is the Windows MDI application style. The WinGLUE® window frame has various parts that manage the overall program, and provides access to the data and program tools.

  • Parts of the programs are accessed by using the program menu and by clicking various command buttons. Most of the program's selections open windows where data can be entered and revised, as well as initiate program calculations.

  • Some of these dialog windows are modal and others are modeless.

  • Model windows are designed so that once you open the window, you may not leave it without closing the window first, usually by pressing "OK" or "Cancel". We have tried to minimize the number of modal windows in WinGLUE®.

  • Modeless windows allow free movement between multiple windows. Most windows in WinGLUE® are modeless. These windows may be left open and allow you to freely access other windows. WinGLUE®'s ability to use modeless panels is due to use of a dependency manager. This guarantees that the solutions are derived from the most recent input data.


  • Interface between Baker Jardine's PipeSim GOAL and WinGLUE® is currently being developed.
    • Benefits: Allows the use of PipeSim GOAL's state of the art optimizer with the most up-to-date gas lift performance data from WinGLUE®. WinGLUE®'s has the most accurate information because WinGLUE® is designed for well surveillance. With WinGLUE® lift gas performance information is being updated and reviewed as new well test becomes available. The link with PipeSim GOAL will allow accounting for produce water and gas constraints. Different optimization scenarios can be run for logistics planning. In addition, the interface:
      • Does not change the operations of either program
      • Provides the ability to store PIPESIM data in a relational database.

  • Dynalift - Dynamic gas-lift simulator is also available. The scientists at Shell International E&P wrote this well simulator.
    • Benefit: It is a great tool for trouble shooting well problems by doing "what-if " type analysis and checking designs for stability before installation. It also, is a good training tool to show new operators and engineers the dynamic behavior of a well with different equipment and operating conditions.


  • Lift Gas Allocation / Optimization:
    • Quick algorithm - optimization for 300 wells in about 3 minutes.
    • Global optimization through exhaustive search of solutions.
    • Ability to export solutions to CAO system to set setpoints on gas injection.
    • Ability to specify minimum injection rate for individual wells - prevents operating in unstable regions.

  • Production Pressure Models
    • MODROS - This is the Modified Ros method, an older, slower empirical model that is included here only for comparison and completeness. It will occasionally be found to be better than the other two models, probably by coincidence.
    • MMSM -The Mobil Moreland Shell Method is a good, quick, empirical model. It has proven to be a very good model for most normal, gas-lifted oil conditions and should normally be used.
    • GZM - The George Zabaras Method is the industry's best model for a variety of conditions. This is a mechanistic model, less based in correlations. For this reason it is particularly good with unusual conditions. GZM is almost as fast as MMSM. It occasionally exhibits some discontinuities at extreme deviations.

  • Graphs
    • Depth vs Pressure

    • This is probably the most important user interface for WinGLUE®. On this window you can consider most aspects of well analysis and design.
    • On the Pressure vs Depth graph you will see several graphics areas.
      • Flowline:
        At the top of the window is the flowline area. The "gauges" show the mainfold pressure (at the far right) and the pressure downstream of the choke and the choke body (in black).
      • Wellbore:
        At the left of the window is the well area. This shows the production (green) and injection (red) areas. At the top of each is a gauge indicating the pressure. The mandrels have hotspots that open the Installed Mandrel table. The blue area is supposed to be for water in the annulus but has no function.
      • Curve Selection
        Any of the following curves can be selected for display:
        • Production Pressure Model
        • Flowing Pressure Survey
        • Static Pressure Survey
        • Static Gradient
        • Injection Pressure Model
        • Installed Mandrels
        • Open/Close Points
        • Equilibrium Curve
        • Design Lines
        • Design Open/Closing Points
        • IPO Injection ROT

    • Depth vs Temperature

    • Accurate temperature prediction is necessary for the best calculation for many gas lift values (e.g. production pressures, gas lift valve pressures). Unfortunately, the accurate calculation of well temperatures requires extensive data inputs and longer computation time. As a compromise, WinGLUE® uses a simple empirical temperature calculation algorithm.

      • Model:
        WinGLUE® contains a simple model for calculation of production temperature. The temperature is based primarily on the production and injection rates, injection depth, tubing size and, to a lesser degree, production casing size.
        The model is based on Joe Clegg's adaptation of a paper by Tulsa University's Sagar, Doty and Schmidt.

    • Pressure vs Production

    • This window is used primarily to view the system solution, i.e. the intersection of the outflow curve and inflow curve, calculated at the bottom of the well. The intersection of the curves gives the system solution, the expected production rate and corresponding flowing bottomhole pressure.

    • Production vs Injection

    • The axes of the graph are oil [and OCI (Operating Cash Income)] on the left and lift gas injection rate on the bottom.

    • Welltest vs Time

    • This window allows you to display, enter and modify values associated with the currently selected Welltest, as well as allowing you to select which welltest will be used in calculations by WinGLUE®.
      • The welltest is the record of measured production rates and pressures for the well on a particular date.
  • Inflow Performance Relationship (IPR)
    • Vogel
