The OPAL acquisition system is based on a modern electronics design in which software control techniques have been used to the best advantage
The hardware incorporates the latest electronic components with embedded systems controlled via the specially developed LoggerSuite windows interface program. The system design philosophy is unique in two respects, firstly it is totally software controlled, and secondly it has been built to accommodate multi-vendor tool types. As standard the OPAL operates all tools using the ALT/MSI QuickLink (QL) protocol, and the PROBE PTX-Intellex and KUSTER telemetry communication protocols. It is also the preferred system to run the Borehole Magnetic Resonance (QL40-BMR60) developed by Qteq.

LoggerSuite Software
LoggerSuite software is compatible with all ALT/MSI data loggers. The software is easy to use and the interface conforms to the Microsoft Windows standard. The heart of the graphical user interface is the dashboard. The operator uses the control panel to select and control all system functions, monitor the data acquisition process and observe the logging tool status. The dashboard consists of multiple threads running concurrently and handling specific system tasks simultaneously.
The dashboard provides access to the following windows :
Browser windows are used for real time data monitoring and offer a wide choice of display and printing options for conventional curves, full waveform sonic traces, acoustic and optical borehole images. A Header Editor is available to provide sophisticated log headers with graphics. Special processors can be activated and configured for real time processing.
WellCAD Browser
WellCAD Browser add-on module allows a real-time connection between the WellCAD data processing platform and the OPAL logger.
- Collect data directly in WellCAD
- Apply templates
- Allow real time editing (annotation)
- Compare currently logged data with reference / repeat data
- QA / QC tasks
- 3D display
- Data preprocessing and field interpretation
In this example, the operator is able to monitor the real time scrolling log, view any or all other logs while monitoring all the log outputs, including depth. Optionally, raw sensor data may be displayed. Comparison with main and repeat sections is possible as well as scrolling and adding annotations while data acquisition continues. Log curve scale and other presentation parameters may be adjusted while logging.
