MagiQ Technologies Taps Sandia Labs for Extreme Seismic Sensor Tests

MagiQ Technologies, the leader in optical sensor innovation for energy, defense, and telecom, announced today that they have successfully demonstrated the high-temperature capabilities of their fiber-optic accelerometers during extensive simulated testing at Sandia National Laboratories.

The goal of the testing at Sandia Labs was to demonstrate that MagiQ's GeoLite (TM) sensors could accurately collect data at extreme temperatures during prolonged exposure, simulating weeks, even months of continuous geothermal data acquisition in extreme, real world scenarios.

Sandia Labs is a National Nuclear Security Administration research and development center with expertise in geosciences and seismology dating back to the 1950s. The testing was conducted at Sandia's primary location in Albuquerque, NM.

The test results confirm that the Company's GeoLite sensors functioned effectively and maintained consistent sensitivity at temperatures exceeding 250°C, proving their viability for extreme geothermal applications. Furthermore, the sensors maintained their sensitivity after prolonged exposure to 300°C for one week, simulating one month of operation at 250°C. This signifies their long-term reliability in the extreme heat found in deep, hot geothermal wells.

Traditional multi-component geophones and Distributed Acoustic Sensors (DAS) experience limited-service life and high failure rates in geothermal wells above 150°C. While DAS sensing has the ability to withstand these high temperatures, they lack the sensor directionality and the sensitivity required for mapping fractures in engineered geothermal systems (EGS).
