– Global positioning system tag – communicates with GPS satellites to establish position with high accuracy, but only when the tag or animal is on land or at the water surface – Fastloc Global positioning system tag – GPS tag for aquatic animals that surface or haul out, when the tag locks onto the GPS satellite network to establish position with high accuracy – Pop-up satellite archival tag – after some period of time recording sensor data, the tag detaches itself from the animal and floats to the surface where it uses satellite connectivity to uplink the data stored on the tag – Acoustic tag – attached to the animals being tracked emit acoustic signals (typically ultrasound) which travel through water much better than RF signals. These signals are then received by buoys, which can then use satellite communications to backhaul the data to where it’s needed.

Fiber-optic Distributed Temperature Sensing (DTS) systems and pressure gauges enable critical monitoring during exploration and energy production for Enhanced Geothermal Systems (EGS). These sensors can be used to: – Estimate production potential in or between new wells by measuring the distributed temperature and the point pressure, or pressure measured at the bottom of the well. These measurements allow the calculation of reservoir size, flow resistance between wells (if multiple wells are instrumented), well bore damage caused by drilling, effectiveness of the fracturing operations, and well completion. – Monitor surface and subsurface scale buildup and chemical clean-up. Scale, a mineral residue precipitated from geothermal fluid in response to changes in water pressure and temperature, builds up on pipe walls and will, over time, form a thick, insulating layer that limits flow and may block a pipe. Chemicals are injected into the pipe to remove the accumulated scale. By understanding severity of the scaling, operators can better consider what mitigation options are most suitable as well as minimize the use of expensive chemicals. – Provide permanent monitoring of injector and producer wells to allow identification of the specific zones and fractures that produce fluids. – Perform integrity monitoring for casing and tubing leaks to avoid contaminating ground water and subsurface aquifers.
