Systems

International Earth Sciences (IESE) manufactures, retails, and installs a wide range of Monitoring instruments/systems for Geotechnical, Geothermal, Seismic, and Telemetry systems.

IESE – INSTRUMENTATION

We help you procure your in-ground or building sensors – we have an international network of suppliers, and where possible we will always get more than one supplier to quote. Piezos, inclos, you name it. And our experience in installations in soft ground with large settlements, with robust QA/QC procedures, helps to increase reliability.

IESE – REMOTE DATA MANAGEMENT

We install Telemetry systems to get your data into the cloud. We can can manage your data, and feed it into any data management and visualization package. But we realise that the data is only as good as the sensors in the ground or in your building. We can help with installations to make sure that data quality is primary.

IESE – MANUFACTURING

Downhole instrumentation for use in micro-earthquake detection. Our Seismometers (Sondes) feature passive sensors with high sensitivity, reliability and longevity, for permanent or temporary installation in hostile borehole environments. We offer to work with clients to develop custom-designed models to satisfy specifications and conditions.

Hydraulic Holelock for Seismometer Coupling

Hole_lockHolelock devices are used to couple sensors at specific depths in boreholes for either short or longer term measurements (<2 years). The simple hydraulic components provide reliability and high coupling force.

High-Pressure and Temperature Borehole Seismometer

s31f-15 The F41-15 is a high-tilt and high temperature triaxial borehole seismometer. It is designed for installation in extreme high-temperature environment up to 150 °C, such as geothermal systems.This model is suitable for test well or behind casing installation.

Shallow Posthole Seismometer

s31f-2.0The F72-2.0 is IESE’s readily deployed shallow posthole sonde for use in micro-earthquake detection and analysis. It is designed for installation in up to 100 m vertical holes. An alternate model, the F72-4.5 offers a higher tilt tolerance in exchange for a higher corner frequency.

Slimhole Seismometer

S51f-4.5 The Model F50-4.5 is a moderate-tilt and moderate-temperature triaxial borehole seismometer. It is designed for installation in temperature environments up to 70 °C, such as geothermal systems. Its primary use is for micro-earthquake detection and analysis.

Borehole Seismometer Observatory Grade

S62g-1.0 Model G202-1.0 is a triaxial borehole seismometer which combines low corner frequency and high-sensitivity. The S62g-1.0 features the highest in-class performance level in sensitivity, reliability and longevity for micro-earthquake detection. A single component G110-1.0 model is also available.

Borehole Seismometer

G88The Model G88-2.0 and G88-4.5 are triaxial borehole seismometers. All three orthogonal component in these models are gimbaled to give borehole deviation. The S22 series models are purpose built for long term or permanent installation in high temperature hostile boreholes.
