Operators can generate a complete four-page well report at the click of a button. Reports are produced in as little as 25 seconds with a 57.6 kbaud connection.
All report data is read directly from the drive using Microsoft Excel and Unico’s free Modbus RTU OPC Server. The software can also use most OPC servers that are readily available for other serial protocols. All sources of serial communication are supported, including wired, modem, radio, and satellite connections.
The Unico Modbus OPC Server can be configured for multiple drives, making the SRP Well Report an inexpensive multiple-well oilfield monitoring system.
On-Line Synchronized Data
The report provides the most comprehensive set of well data available today. While similar, more expensive applications estimate well operating conditions off-line (such as gearbox torque), none of the values in the SRP Well Report are estimated. All of the information provided is measured. Data and charts are fully synchronized so that each report represents one complete cycle of the pump.
Easy Status Monitoring
The report presents a wide variety of information in an easy-to-read format that makes monitoring well operating status a breeze. The report includes:
Measured surface and downhole DynaCard including unit rated rod load
Measured gearbox torque chart including pump direction and unit rated torque plots.
Reference input chart
Gearbox torque chart including measured gearbox torque, counterbalance assist torque, and as-balanced torque plots
Velocity chart including rod velocity, downhole pump velocity, and crank velocity plots
Predicted surface and downhole DynaCards with pump-off (incomplete pump fill) simulation

The SRP Well Report can be viewed in either English or Spanish with the click of a button.
The full set of time-stamped well data can be exported to .txt text files for easy archiving. An import feature reads these files and reformats them into the well report format. Data can also be exported as .dyn files that can be imported into Theta’s Rodstar and other applications.
Open Source Code
The software’s Microsoft Visual Basic for Applications source code is open for customization. The code is password-protected to avoid accidental changes. The Excel file has a read-only attribute to avoid accidental changes. The software is fully programmable to read from or write to any item in the drive’s dictionary. Sample code is provided for easy cut-and-paste modifications. The Unico Modbus OPC Server supports all necessary operations (array/vector processing) to produce these reports via serial/radio transmission. The Excel/VBA application supports most generic OPC servers, allowing other communication protocols or data transmission methods to be used.
