MAST cavity-ring-down spectroscopy-based sensor to detect oil-drilling tracer nanoparticles

Through its subsidiary Micromem Applied Sensor Technologies (MAST), Micromem Technologies (CSE:MRM) (OTCBB:MMTIF) has executed a memorandum of understanding with Entanglement Technologies (Burlingame, CA), a trace-gas-sensor research and development company, to develop a so-called "interwell tracer in-line field-hardened sensor detection platform" for the oil industry.

In interwell tests, a tracer substance is injected in one oil well and then follows underground flow routes, appearing later at another oil well. Sensing the substance there helps oil companies understand the underground geology and oil-flow routes and rates.

The MAST sensor platform will detect nanometer-sized magnetic particles at concentration of less than 1 part per billion. The scaling and industry-wide deployment of nanoparticles as a viable alternative to current interwell tracers remains a challenge that the oil industry continues to commit significant resources to. MAST is also now working with its clients in developing the nanoparticles.

"This novel technology, combining the best features of cavity-ring-down spectroscopy and gas chromatography, is rapidly developing to replace entrenched sensing technologies," says Tony Miller, CEO of Entanglement Technologies. "This solution will transform the tracer detection landscape by allowing for real-time autonomous well-head sampling and analysis of produced fluid for ongoing reservoir monitoring, management, and intelligence. Providing producers with high quality real time data will enhance well productivity and reservoir management. Entanglement Technologies is proud to partner with MAST to bring this technology into a new market."

The in-line product is scheduled for field trials within a year. MAST has the responsibility for deploying this technology to the industry.
