Fiber optics sensing technology has revolutionized the way we monitor hydraulic fracturing of unconventional reservoirs and enhanced geothermal systems. ESG’s Fusion ArrayTM acquires fiber and geo phone data in the same well, which allows operators to maximize subsurface diagnostic data in the same well footprint. Optical fiber is used to acquire distributed acoustic sensing (DAS) and distributed temperature sensing (DTS). DAS data is primarily used for cross-well strain and microseismic monitoring during hydraulic fracturing, while DTS data is used for temperature monitoring.This technology requires an optical fiber installed permanently behind the casing, or temporarily in the offset well and an interrogator on the surface.Fiber optic data can be acquired on dedicated or in wireline conveyed fibers.The entire length of fiber acts as a continuous one component sensor.
