Fiber-optic Distributed Temperature Sensing (DTS) systems and pressure gauges enable critical monitoring during exploration and energy production for Enhanced Geothermal Systems (EGS).

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.
