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
- Disk Space
- 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
- 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’s computer
- 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
- Populate databases through importation of data from Microsoft Excel-style "csv"
- 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
- 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
- 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
- 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.
- 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.
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).
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.
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)
