Downhole memory tools specialist Omega Well Monitoring has launched the patents-pending Leakator, a tool optimised to locate leaks and monitor downhole flow.
Omega said Leakator’s run-it-yourself capability means an existing on-site crew can operate the tool without the need for further staff. Easy to maintain, it has no moving parts – only the o-rings and detachable batteries need to be replaced during servicing – and requires just small AA batteries.
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 and indicate leaks. Optional sensor modules enable additional data to be monitored, including differential temperature, flow and flow direction. According to Omega, a Reservoir Group division, 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 tool’s 25mm diameter means it can access all zones.
