Omega Well Monitoring, a member of international oilfield services company, Reservoir Group, and specialist in the manufacture and supply of downhole memory tools, has announced the launch of its latest product, the Leakator.
The tool, for which patents are pending, is optimised to locate leaks and monitor downhole flow. It has been developed in response to the increasing requirements of the industry to improve efficiency and reduce operating costs, by monitoring well integrity. The Leakator’s run-it-yourself capability means an existing on-site crew can operate the tool without the need for further staff. It is easy to maintain. No moving parts mean that only the o-rings and detachable batteries need to be replaced during servicing. And as a result of its small AA batteries, operators do not need to comply with dangerous goods legislation during transportation. This means operators can commit less time and staff to the job.
A modular memory instrument, the Leakator uses multiple sensor arrays, with synchronised data from the sensors merged and plotted against depth to highlight local variations in the well. This provides an indication of leaks. Optional sensor modules enable additional data to be monitored, including differential temperature, flow and flow direction. The sensors are physically distributed and have a balanced output, allowing extreme sensitivity to very small local anomalies of temperature and flow. A surface read out capability is also possible.
As a result of the modular assembly, operators can customise the set-up to fit the specific requirements of each individual job, determined by the various well conditions. And the Leakator’s 25mm diameter means it can access all zones. Neil Matheson, managing director of Omega Well Monitoring, said: “The Leakator is a must have technology for oil and gas operators looking for improved well monitoring. Its ability to protect well integrity by detecting leaks, while also allowing operators to monitor flow and temperature will provide substantial benefits in terms of improving efficiency and enabling cost savings.”
