DTS-BLY-5S (CT-10km) · Temperature-stabilized DTS for oil & geothermal wells
Temperature-stabilized configuration for oil-well and geothermal temperature profiling.
Constant-Temperature Distributed Temperature Sensing (DTS) System for Oil & Geothermal Applications
Constant-Temperature Distributed Temperature Sensing (DTS) System for Oil & Geothermal Applications
Model: DTS-BLY-5S (CT-10km)
Measures continuous temperature profiles and abnormal-temperature locations along the fiber. Select range, fiber type, channels and sensing cable for the specified model.
Typical applications
Downhole geothermal wells, downhole oil wells, CCUS projects, gas storage facilities, compressed air energy storage systems, and other applications with higher requirements for absolute temperature accuracy.
Spatial resolution, sampling interval and location accuracy are distinct quantities. Temperature accuracy depends on fiber length, acquisition time, temperature range and cable configuration; optimum values are not necessarily simultaneous.
Spatial resolution uses the 10%–90% step-response criterion and the ± spatial-extent notation used in this datasheet. Location accuracy is specified separately. Compare specifications using the same definitions and test conditions.
