Windows based communications software packages are available that allow configuration of controllers and data loggers and data retrieval. The software can be loaded on laptop or palmtop PC's or on Host computers if a means of communication to the controller at the well site is available.

COSCO "Communicator" software allows communication with Vortex Controllers and COSCO data loggers simultaneously and seamlessly.

Vortex motor control parameters may be configured by the Vortex display or by use of the software, Data logging parameters and alarms based on analog readings from transducers or bottom hole sensors are configured using the Communicator software package.

The following gives some examples of software screens and a brief overview of how the software is used to configure controller alarm set points and data logging parameters.

The Alarms Setpoints screen shown at right is used to set standard ESP alarm set points.

Set points, trip delays and trip acceleration curves may all be adjusted using these screens.

 

 

 

 

The General Parameters screen shown at right is used to set up parameters such as maximum starts, restart delays etc.

Record Options

The Record Options Screen is used to set up data logging functions, and requires that the COSCO Communicator data logger or a computer be connected to the controller. (A computer connected remotely can perform the data logging function).

The parameters to be recorded, and the interval for raw data (sampling rate) are set up using this screen.

Graph labels for each logged parameter may also be set up by the user.

If a down hole sensor or pressure transducers are connected, windows for the appropriate parameter set points also appear.

The parameter labels specified appear in the data logging table as shown below

The above screen is used to retrieve logged data from the Data Logger's memory, the time interval for the data to be retrieved is specified in the windows at the top of the screen.

Retrieved data may be saved into Excel spreadsheet format or the graphing functions of the Communicator software may be used to generate graphs. Graphing may also be accomplished in Excel as shown later in this document.

Event Logs are used to record the time and date of events such as shutdowns (and their reasons), starts, and to identify when analog readings not set to shut down the unit exceed user determined values. The Event Log calls the users attention to the time and date of data that needs to be reviewed.

Data recorded at faster sampling rates surrounding each event (recorded in the circular buffer) can also be viewed allowing detailed analysis of data related to alarms.

The Event Log requires that the COSCO data logger be connected, it adds the real time capability to the Vortex controller.

The Communicator software allows the user to quickly and simply generate commonly used graphs such as weekly amperage charts.

The graph shown opposite is a 24 hour amp chart shown in traditional circular format.


The style of chart desired can be changed by using the Chart Control Properties screen shown opposite.

Data retrieved can be saved in Excel worksheet format with the Time and Date stamp shown in Column A and all other measured parameters are shown in individual columns named according the to parameter name as the input was configured.

This data may be reviewed, graphed, saved or e-mailed, limited only by the user's knowledge of Excel.

Graphing is most easily accomplished by using the Excel Chart Wizard. All parameters to be graphed can be highlighted by clicking on the column (A, B etc) while holding down the Control key then clicking on the Chart Wizard Icon.

The example shown above is from a well with a down hole sensor connected. Bottom Hole Pressure (BHP), Temperature (BHT) and Motor Temperature (MTR) are being logged as well as voltage, current and power consumption data.


As shown in the above example, the Time Stamp, Current on Phases A, B, C, Bottom Hole Temperature, Pressure and Motor Temperature parameters have been chosen to be graphed together by holding down the Control Key and clicking on the column heading. Clicking on the Chart Wizard Icon brings up step one of graphing the data.

For this type of graph it is best to choose the Line Graph option with the first Chart sub option. For circular amp charts Radar charts are best.

Graph line types, colours, line width, labels, comments etc. may all be adjusted using Excel features.

For regular users, macros for common graphing tasks can be written and used.
