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.
